| CVE-2026-87864 | 1 Curl | 1 Curl | 2026-10-30 | 8.1 High |
| Enabling `CURLOPT_CRLF` causes curl to advertise the raw input byte count in the `IMAP APPEND {N}` literal while transmitting line-ending expanded data. The server reads only $N$ bytes for the payload, causing the remaining overflow bytes to be interpreted and executed as pipelined IMAP commands within the authenticated session. | ||||
| CVE-2026-87863 | 1 Curl | 1 Curl | 2026-10-30 | 8.1 High |
| An authenticated HTTPS origin can supply an HSTS `max-age` value that the parser accepts, but time serialization later fails to process. On 64-bit systems, extreme max-age values compute an absolute expiry within standard time integer limits that exceeds calendar time structure bounds. During cache saves, the original HSTS file is truncated before writing a temporary replacement; when serialization fails, the temporary file is deleted, leaving an empty or partial cache. Because the save error is silently ignored during cleanup, curl exits successfully despite the data loss. | ||||
| CVE-2026-87862 | 1 Curl | 1 Curl | 2026-10-30 | 8.1 High |
| Importing a `includeSubDomains` parent HSTS entry before a longer-lived child entry, silently drops the child. Consequently, when the parent expires, the child's valid HSTS policy is lost, causing curl to issue unencrypted HTTP requests rather than upgrading to HTTPS. | ||||
| CVE-2026-86415 | 1 Curl | 1 Curl | 2026-10-30 | 7.5 High |
| libcurl's connection cache match function never considers the automatic client certificate option, so a cached, already authenticated Schannel connection can be handed to a transfer that got redirected to a different origin, even though the code explicitly switched off the auto client cert option for that transfer to prevent exactly this. | ||||
| CVE-2026-119408 | 1 N8n | 1 N8n | 2026-10-30 | 8.8 High |
| n8n before 2.42.6, 2.43.x before 2.43.3, and 3.x before 3.0.1 contains a remote code execution vulnerability via deprecated Function, Function Item, and LangChain Code nodes running outside task runner isolation. Authenticated users who can create, modify, or import workflows naming these hidden node types can execute JavaScript in the n8n main process. | ||||
| CVE-2026-81726 | 1 Nltk | 1 Nltk | 2026-10-30 | 7 High |
| NLTK through 3.10.3 contains a path traversal vulnerability in model-artifact APIs that bypass pathsec enforcement by using raw file operations on caller-controlled paths. Attackers can read or write files outside allowed sandbox roots through TransitionParser, AveragedPerceptron, PerceptronTagger, and maxent parameter APIs when pathsec is enabled. | ||||
| CVE-2026-110681 | 1 Rurban | 1 Cpanel::json::xs | 2026-10-30 | 8.1 High |
| Cpanel::JSON::XS versions before 4.80 for Perl use the parent interpreter's scalars from a parser object cloned into a new ithread. A parser object holds its callbacks and its incremental parse buffer as raw scalar pointers. When a thread is created, these are copied into the new interpreter unchanged, so the child's parser uses, and later frees, scalars that belong to the parent and may already have been freed there. A parser created before a thread starts and used inside it can call freed callbacks, corrupt reference counts and crash the process. | ||||
| CVE-2026-110680 | 1 Rurban | 1 Cpanel::json::xs | 2026-10-30 | 7.5 High |
| Cpanel::JSON::XS versions from 4.20 before 4.80 for Perl write out of bounds when a tied or shared hash grows during canonical encoding in encode_hv. With canonical, the keys of a tied or threads::shared hash are counted before a second pass collects them for sorting. The encoder uses a fixed 64-entry stack array or, for larger counts, a heap array sized from the first pass. If the second pass exceeds that capacity, entries are written out of bounds before the counts are compared. This corrupts stack or heap memory and can crash the process. | ||||
| CVE-2024-9287 | 2 Python, Redhat | 3 Python, Enterprise Linux, Rhel Eus | 2026-10-30 | 7.8 High |
| A vulnerability has been found in the CPython `venv` module and CLI where path names provided when creating a virtual environment were not quoted properly, allowing the creator to inject commands into virtual environment "activation" scripts (ie "source venv/bin/activate"). This means that attacker-controlled virtual environments are able to run commands when the virtual environment is activated. Virtual environments which are not created by an attacker or which aren't activated before being used (ie "./venv/bin/python") are not affected. | ||||
| CVE-2026-76418 | 1 Cisco | 3 Adaptive Security Appliance Software, Cisco Secure Firewall Threat Defense (ftd) Software, Secure Firewall Threat Defense | 2026-10-30 | 8.6 High |
| A vulnerability in the Remote Access SSL VPN service of Cisco Secure Firewall Adaptive Security Appliance (ASA) Software and Cisco Secure Firewall Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause the device to reload unexpectedly, resulting in a denial of service (DoS) condition. This vulnerability is due to logic errors when secondary authentication is configured on a tunnel group. An attacker could exploit this vulnerability by sending a crafted request when connecting to the SSL remote access VPN. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition. | ||||
| CVE-2026-101295 | 2 Oc-mirror, Redhat | 4 Oc-mirror, Assisted Installer, Openshift and 1 more | 2026-10-30 | 7.3 High |
| Path traversal / arbitrary file write in oc-mirror's operator catalog image extraction. When mirroring operator catalogs using either the legacy v1 path (--v1) or the OCI feature path (--use-oci-feature), oc-mirror extracts tar entries from catalog image layers without validating that file paths resolve within the intended destination directory. | ||||
| CVE-2026-102010 | 2 Gnu, Redhat | 6 Gcc, Enterprise Linux, Hardened Images and 3 more | 2026-10-30 | 7 High |
| A flaw was found in GCC. When an application calls the erase_if function on a binary heap priority queue in libstdc++, the library reallocates storage but fails to update its internal entry pointer. An attacker capable of triggering this operation can exploit this use-after-free condition, leading to a Denial of Service (DoS) via an application crash or potential memory corruption. | ||||
| CVE-2026-58014 | 2 Gnome, Redhat | 18 Glib, Ai Inference Server, Cert Manager and 15 more | 2026-10-30 | 7.3 High |
| A flaw was found in GLib. An off-by-one error can occur in the g_key_file_get_locale_string_list function in the gkeyfile.c file when loading a key file with an empty value. This flaw can cause an out-of-bounds access of 1 byte or a denial of service when the out-of-bounds access crosses a page boundary. | ||||
| CVE-2026-42013 | 2 Gnu, Redhat | 17 Gnutls, Cert Manager, Discovery and 14 more | 2026-10-30 | 8.2 High |
| A flaw was found in gnutls. When validating certificates, an oversized Subject Alternative Name (SAN) could cause the validation process to incorrectly fall back to checking the Common Name (CN) field. This could allow a remote attacker to bypass proper certificate validation, potentially leading to spoofing or man-in-the-middle attacks. | ||||
| CVE-2026-42011 | 1 Redhat | 16 Cert Manager, Discovery, Enterprise Linux and 13 more | 2026-10-30 | 7.4 High |
| A flaw was found in gnutls. This vulnerability occurs because permitted name constraints were incorrectly ignored when previous Certificate Authorities (CAs) only had excluded name constraints. A remote attacker could exploit this to bypass critical name constraint checks during certificate validation. This bypass could lead to the acceptance of invalid certificates, potentially enabling spoofing or man-in-the-middle attacks against affected systems. | ||||
| CVE-2026-5260 | 2 Gnu, Redhat | 16 Gnutls, Cert Manager, Discovery and 13 more | 2026-10-30 | 8.2 High |
| A flaw was found in libgnutls. A remote attacker, by sending an extremely short premaster secret during an RSA key exchange to a server using an RSA key backed by a PKCS#11 token, could trigger a short heap overread. This memory corruption vulnerability could lead to information disclosure. | ||||
| CVE-2026-95619 | 1 Redhat | 5 Enterprise Linux, Hardened Images, Hummingbird and 2 more | 2026-10-30 | 7.7 High |
| A flaw was found in libstdc++. An integer overflow can occur when processing large inputs to the aligned operator new in the C++ library. This vulnerability could lead to an undersized memory allocation, potentially causing memory corruption or application instability. | ||||
| CVE-2026-104795 | 1 Redhat | 1 Openshift | 2026-10-30 | 8.8 High |
| The insights-runtime-extractor runs as a privileged DaemonSet (`hostPID: true`) that scans container processes for runtime fingerprinting. When scanning a container, the coordinator: 1. **fork()s** a child process 2. **setns()** into the target container's PID and mount namespaces 3. **fchdir()** back to an orphaned FD pointing at the extractor's own root filesystem (where `/crio.sock` is hostPath-mounted) 4. Calls **only `seteuid(target_uid)`** — changing the effective UID but leaving the **real UID and saved-set-UID at 0** and **retaining the permitted capability set** 5. The `check_no_privileged_perms()` guard inspects only the Effective capability set (so it passes), and is **skipped entirely when the target runs as uid 0** 6. The `VersionExecutable` fingerprint invokes `fpr_kind_executable` with `process.command_line[0]` — the target's argv[0], read from `/proc/<pid>/cmdline` and **fully controlled by the workload** 7. `fpr_kind_executable` calls `exec.Command(executable, "--version").Output()` — executing the **workload's own binary** inside the workload's mount namespace while **ruid=0 in the host user namespace** The executed process can call `setuid(0)` to restore full root with `CAP_SYS_ADMIN`, and inherits the orphaned cwd which resolves into the extractor container's filesystem containing the host CRI-O socket. ## Affected Code ### 1. Insufficient privilege drop (Rust — extractor coordinator) **File:** `extractor/src/insights_runtime_extractor.rs` ```rust // Lines 139-146 — seteuid-only drop, guard skipped for root containers join_process_namespaces(process.pid)?; change_dir(current_dir); switch_user(*process.uid)?; if *process.uid != 0 { perms::check_no_privileged_perms() .expect("Must not have privileged permissions to run fingerprints"); } fingerprint::run_fingerprints(&config, out_dir, &process); ``` ```rust // Lines 182-185 — only effective UID changed; ruid/suid stay 0 fn switch_user(uid: u32) -> Result<(), ScannerError> { debug!("... Becoming user: {uid}"); seteuid(uid.into()).map_err(|e| ScannerError::Errno(e)) } ``` ### 2. Execution of untrusted binary (Go — fingerprint) **File:** `fingerprints/pkg/utils/file.go` ```go // Lines 75-80 — executes a path taken verbatim from workload's argv[0] func GetExecutableVersionOutput(executable string) (string, error) { out, err := exec.Command(executable, "--version").Output() if err != nil { return "", err } return string(out), nil } ``` ### 3. Workload-controlled path forwarded (Rust — version_executable) **File:** `version_executable.rs` ```rust // Lines 29-34 — workload-controlled command_line[0] forwarded to fingerprint return Some(vec![ fpr_kind_executable, out_dir.to_string(), String::from(&process.command_line[0]), String::from(&version_executable.runtime_kind_name), ]); ``` ## Attack Pattern **Attacker:** Any tenant able to schedule a pod (unprivileged, any namespace) **Victim:** The node running the insights-runtime-extractor DaemonSet **Trigger:** Automatic — the DaemonSet scans all container processes on the node **Attack sequence:** 1. Attacker creates a pod whose process name matches a configured versioned-executable pattern (`node`, `python`, `python3`, `MainThread`, or contains `java`) 2. The pod's main binary (at the path matching argv[0]) is a malicious executable that calls `setuid(0)` to restore root 3. When the insights operator triggers a scan, the DaemonSet forks, enters the attacker's mount namespace, and executes the attacker's binary with ruid=0 4. The attacker's code regains full root with `CAP_SYS_ADMIN` in the host user namespace 5. The inherited cwd contains the host CRI-O socket → full node compromise | ||||
| CVE-2026-93017 | 1 Redhat | 2 Openshift, Openshift Container Platform | 2026-10-30 | 7.7 High |
| The `insights-operator-gather` ClusterRole grants the operator's service account read access to secrets in the core API group with no namespace or resourceNames restriction — therefore, access to every secret in every namespace in the cluster. Ref: https://github.com/openshift/insights-operator/blob/8f15e3157ff09f54ab22801f5b21da35a195cc6d/manifests/03-clusterrole.yaml#L368-L373 ``` - apiGroups: - "" resources: - secrets verbs: - get - list ``` By spawning a pod with the gather service account mounted, an attacker will be able to access any secret in any namespace. ``` spec: serviceAccountName:"gather" ``` | ||||
| CVE-2026-75888 | 1 Redhat | 2 Openshift, Openshift Container Platform | 2026-10-30 | 7.7 High |
| A flaw was found in the OpenShift console. An authenticated console user can exploit a Server-Side Request Forgery (SSRF) vulnerability by providing a specially crafted Helm chart URL without proper validation. This allows the user to make the console pod fetch arbitrary URLs, potentially leading to the disclosure of sensitive information through error messages or enabling blind port scanning within the cluster. | ||||
