CVE-2026-59809 2 B3log, Siyuan 2 Siyuan, Siyuan 2026-08-23 4.9 Medium
SiYuan before v3.8.0 interpolates secret placeholders into the destination URL parameter of the http_request MCP tool, allowing attackers to exfiltrate stored secrets. An MCP client can craft a request with an attacker-controlled URL containing secret placeholders to send plaintext secret values to any public host without confirmation.
CVE-2026-77088 1 Emilstenstrom 1 Justhtml 2026-08-23 6.1 Medium
justhtml versions 0.9.0 through 1.21.0 contain a cross-site scripting vulnerability in to_markdown() where inline code spans fail to account for blank lines as block boundaries. Attackers can inject blank lines into code or pre element text to break the inline span, causing sanitized HTML to be emitted unescaped and re-parsed as live Markdown by compliant renderers.
CVE-2026-50290 1 Asymmetric-effort 1 Specifyjs 2026-08-23 N/A
SpecifyJS is a declarative TypeScript user interface framework. Prior to version 0.2.136, CSS value sanitization stripped `expression(` and `url(javascript:` using simple regex, but could be bypassed with CSS unicode escapes (`\65xpression(`), null bytes, or CSS comments (`exp/**/ression(`). These CSS injection vectors only work in legacy browsers (IE6-IE10). SpecifyJS targets modern browsers. Starting in version 0.2.136, CSS sanitization now normalizes unicode escapes and strips CSS comments before pattern matching. Also checks for `behavior:`, `-moz-binding`, and `-o-link` patterns.
CVE-2026-77811 2 Aws, Opensearch 3 Amazon Opensearch Service, Opensearch Dashboards, Opensearch Dashboards Dashboards-observability Plugin 2026-08-23 8.7 High
Improper input validation in the dashboards-observability plugin in OpenSearch Dashboards allows a remote authenticated user with write permissions to OpenSearch Dashboards saved objects to execute arbitrary JavaScript in the context of other users' browser sessions by uploading a saved asset with arbitrary web content.
CVE-2026-68508 1 Facebookresearch 1 Hydra 2026-08-23 7.8 High
Hydra is a framework for elegantly configuring complex applications. Prior to 1.3.4, hydra.utils.instantiate() resolves and calls Python objects selected by configuration through _resolve_target() in hydra/_internal/instantiate/_instantiate2.py, allowing attacker-controlled target values and arguments to choose dangerous callables. A consuming application, library, CLI workflow, or model loader that passes untrusted configuration, CLI overrides, or model metadata into hydra.utils.instantiate() can therefore execute arbitrary code in its own process, including reading or modifying files and credentials or terminating the process. Version 1.3.4 adds target blocking with an explicit HYDRA_INSTANTIATE_ALLOWLIST_OVERRIDE escape hatch. This issue is fixed in version 1.3.4.
CVE-2026-44517 1 Containers 1 Buildah 2026-08-23 6.3 Medium
Buildah is a tool that facilitates building OCI images. From 1.38.1 until 1.43.2 and 1.44.0, TempDirForURL in define/types.go does not securely confine Git repository subdirectories to the downloaded build context, and downloadToDirectory and stdinToDirectory can follow a Dockerfile symlink left by a partially extracted tar archive. A malicious server supplying a Git repository or tar archive can cause files outside the build context directory to be included in the context or copied into the build. This issue is fixed in versions 1.43.2 and 1.44.0.
CVE-2026-53656 1 Voxel51 1 Fiftyone 2026-08-23 6.3 Medium
FiftyOne is an open-source platform for refining high-quality datasets and visual AI models. Prior to 1.17.0, the FiftyOne App/API server in fiftyone/server/app.py and the /media route in fiftyone/server/routes/media.py unconditionally return Access-Control-Allow-Origin: *. Because the embedded server is local and unauthenticated, a malicious website visited by the user can read cross-origin responses. The /media endpoint accepts a filesystem path, allowing a drive-by page to read files accessible to the server process and exfiltrate them without additional clicks. The allowed_origins configuration and FIFTYONE_ALLOWED_ORIGINS environment variable now make cross-origin access explicit, while the default policy is same-origin. This issue is fixed in version 1.17.0.
CVE-2026-53529 1 Perber 1 Leafwiki 2026-08-23 N/A
LeafWiki is a self-hosted wiki. Prior to version 0.10.2, page titles returned by the search API could be rendered as raw HTML in the frontend. A user with editor or administrator permissions could create or modify a page title containing an HTML/JavaScript payload. When another user searched for a matching term, the payload could execute in the victim’s browser. The impact depends on deployment configuration. With `--public-access` enabled, unauthenticated visitors could be affected. In authenticated-only deployments, the issue could be used for cross-user XSS against logged-in users who can access search results. The issue has been fixed in version 0.10.2 by ensuring that author-controlled page titles in search results are not interpreted as raw HTML by the browser while preserving search result highlighting.
CVE-2026-53531 1 Erweixin 1 Ratex 2026-08-23 N/A
RaTeX is a KaTeX-compatible math rendering engine written in Rust. Prior to version 0.1.11, RaTeX’s recursive-descent parser recurses one (or more) native stack frame per nesting level at `{`, `\left`, `\sqrt{`, `^{`, etc, with no maximum depth limit. A short, ~10 KB input of nested groups overflows the 8 MB main-thread stack and aborts the process. With `panic = "abort"` (`Cargo.toml:48`), and because a Rust stack overflow is always a fatal `SIGABRT` regardless of panic strategy this is an unrecoverable, whole-process denial of service reachable from a single untrusted LaTeX string. Version 0.1.11 fixes the issue.
CVE-2026-48050 1 Basekick-labs 1 Arc 2026-08-23 N/A
Arc is an open, SQL-native time-series database for telemetry. Versions prior to 26.06.1 register Go's `net/http/pprof` handlers at `/debug/pprof/*` via `app.Use(pprof.New())` in `internal/api/server.go`, and `/debug/pprof` is added to `PublicPrefixes` in `cmd/arc/main.go`. The auth middleware short-circuits before the token check on prefix match, so the endpoints are reachable without any authentication. Version 26.06.1 contains a patch. Some workarounds are available. Block `/debug/pprof*` at a reverse proxy / load balancer in front of Arc, restrict Arc's API port to known-trusted networks via firewall rules, and/or patch the running build: comment out `app.Use(pprof.New())` in `internal/api/server.go` and rebuild.
CVE-2026-57998 1 Jeemok 1 Better-npm-audit 2026-08-23 7.8 High
better-npm-audit through 3.11.0, and the 4.0.0-rc.2 prerelease, builds its npm audit command by interpolating the user-supplied --registry option into a command string in src/handlers/handleInput.ts without validation or quoting, then passes that string to child_process.exec() in index.ts, which spawns a shell. A registry value containing shell metacharacters such as a semicolon, pipe, or command substitution executes arbitrary operating system commands with the privileges of the process running the audit.
CVE-2026-5388 1 Emilstenstrom 1 Justhtml 2026-08-23 9.8 Critical
justhtml before 1.15.0 contains multiple security issues in URL sanitization helpers (clean_url_value/clean_url_in_js_string), HTML serialization, Markdown passthrough (html_passthrough=True), and several custom sanitization-policy edge cases. Depending on configuration, an attacker can bypass sanitization to inject active HTML and JavaScript — for example via encoded javascript: URLs, backslash-based relative URLs resolved as remote hosts, markup-breaking programmatic element/attribute names or HTML comments, raw </textarea> reintroduction through Markdown passthrough, or preserved <style>/<meta http-equiv=refresh>/<base href> tags in custom policies. Most custom-policy issues do not affect the default sanitize=True configuration; they primarily affect helper APIs, programmatic DOM construction, html_passthrough=True, and custom policies/transform pipelines.
CVE-2026-77116 1 Brave 1 Brave 2026-08-23 4.3 Medium
Brave Popup Builder (slug: brave-popup-builder) has a broken access control issue in versions through 0.8.5. Any logged-in user - Subscriber or WooCommerce Customer is enough — can read popup content they shouldn't have access to by passing a post ID in the URL.
CVE-2026-77115 1 Brave 1 Brave 2026-08-23 7.1 High
Brave Popup Builder (brave-popup-builder) up to version 0.8.5 reflects UTM query parameters into popup form HTML without escaping them.
CVE-2026-77002 2026-08-23 9.8 Critical
The SmilePass Selfie Login WordPress plugin through 1.0.2 does not perform any server-side verification of the identity it is asked to authenticate, allowing unauthenticated users to log in as any registered account, including administrators.
CVE-2026-77000 2026-08-23 9.8 Critical
The WP Social Media Login WordPress plugin through 1.0.6 does not verify that a social login was actually completed with the identity provider before authenticating a visitor, allowing unauthenticated attackers to log in as any existing user, including administrators, by supplying that user's email address.
CVE-2026-19221 2026-08-23 7.2 High
The Forminator Forms WordPress plugin before 1.57.0.5 does not restrict a network-wide setting to network administrators, allowing an administrator of any single site on a multisite network to execute arbitrary code across the entire network.
CVE-2026-16260 2026-08-23 6.8 Medium
The Post Grid, Slider & Carousel Ultimate WordPress plugin before 1.8.1 does not sanitise and escape one of its custom post type settings before outputting it in an HTML attribute on the admin edit screen, allowing users with the Contributor role and above to inject JavaScript that executes in the session of any administrator who opens the affected item.
CVE-2026-76613 1 Yootheme.com 1 Yootheme Pro Extension For Joomla 2026-08-23 N/A
Joomla Extension - yootheme.com - Authenticated, privileged SQL injection in YOOtheme Pro 1.0.0-5.0.40 - An SQL injection allowed any contributor-level user to inject own content into SQL queries.
CVE-2026-74600 1 Linux 1 Linux Kernel 2026-08-23 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: mm/page_table_check: skip special zero mappings page_table_check_set() and page_table_check_clear() account mappings based on PageAnon(). Shared zero-page PTEs and huge zero PMDs are special mappings, but page_table_check can still account them as file-backed pages. An unprivileged process can populate enough zero mappings to overflow file_map_count and hit the existing BUG_ON(). The PTE path can do this with the shared zero page, and the PMD path can do the same with huge zero mappings. Skip special zero mappings in the user page-table accounting paths. Keep the PTE-side pte_special() check, and identify huge zero PMDs from the mapped folio instead of pmd_special(). That covers architectures where pmd_special() is a no-op without adding huge_zero_pfn checks to the generic counter helpers.
