CVE-2026-100678 1 Stoatchat 1 Stoatchat 2026-09-26 6.5 Medium
stoatchat before 0.15.5 fails to enforce account-level attempt limits on MFA login challenges, allowing attackers who know a password to guess TOTP codes with only IP-based rate limiting. Attackers can reuse MFA challenge tickets across multiple failed attempts and distribute guesses across IP addresses to bypass rate limiting and gain account access.
CVE-2026-100677 1 Stoatchat 1 Stoatchat 2026-09-26 5.3 Medium
stoatchat before 0.15.5 contains an account enumeration vulnerability in the login endpoint that exposes source file locations in error responses. Unauthenticated attackers can distinguish between registered and unregistered email addresses by comparing error location fields returned from POST /api/auth/session/login requests.
CVE-2026-100674 1 Stoatchat 1 Stoatchat 2026-09-26 4.3 Medium
stoatchat before 0.15.5 fails to revalidate usernames after Unicode sanitization, allowing attackers to create usernames with forbidden characters by submitting Unicode letters that transform into rejected characters. Attackers can bypass character allowlists and length limits to create reserved-name lookalikes, embed special characters, and exceed the 32-character storage limit.
CVE-2026-100675 1 Stoatchat 1 Stoatchat 2026-09-26 6.5 Medium
stoatchat versions before 0.15.5 contain a denial of service vulnerability in the acknowledgement worker that processes mass mention messages. Authenticated users can send five crafted role-mention messages to terminate all acknowledgement workers, disabling push notifications and mention badges deployment-wide until the API process restarts.
CVE-2026-100676 1 Stoatchat 1 Stoatchat 2026-09-26 8.2 High
January, the media proxy/embed service of stoatchat (stoatchat/stoatchat), before version 0.15.5 improperly resolves SVG <image href> values as local filesystem paths when a fetched resource is served as image/svg+xml. An unauthenticated remote attacker who causes the service to proxy an attacker-hosted SVG (e.g. via the /proxy endpoint) can determine whether local files exist through observable response-time differences, and can cause supported local image files to be disclosed after re-encoding. Because each referenced file is read in full with no effective limit on the number or total volume of reads, a single request can also generate an unbounded amount of local filesystem I/O and memory pressure (the published proof of concept drives about 4.34 GB of reads), leading to denial of service. The issue is fixed in 0.15.5.
CVE-2026-100679 1 Stoatchat 1 Stoatchat 2026-09-26 8.8 High
stoatchat before 0.15.5 fails to validate that MFA tickets belong to the authenticated user, allowing attackers to bypass MFA by using their own valid ticket with another user's session token. Attackers can obtain a ticket from their own account and use it with a victim's session token to disable TOTP, view recovery codes, or perform other sensitive operations without providing the victim's credentials.
CVE-2026-73057 1 Stoatchat 1 Stoatchat 2026-08-18 7.5 High
stoatchat before 0.15.0 fails to validate SVG viewBox dimensions in the proxy endpoint, allowing attackers to cause denial of service by memory exhaustion. Attackers can host malicious SVGs with extremely large width and height values and trigger concurrent requests to exhaust available memory across proxy replicas.
CVE-2026-73058 1 Stoatchat 1 Stoatchat 2026-08-17 5.8 Medium
stoatchat versions before 0.15.0 fail to block the IPv6 unspecified address (::) in the SSRF blocklist, allowing unauthenticated attackers to bypass protections via the /proxy and /embed endpoints. Attackers can craft requests using IPv6 literal syntax to access services on the loopback interface and retrieve sensitive internal content.
CVE-2026-74869 1 Stoatchat 1 Stoatchat 2026-08-17 7.7 High
stoatchat before 0.15.0 contains a missing authorization vulnerability in the Subscribe message handler that allows authenticated attackers to enumerate members and monitor profile updates of private servers without membership. Attackers can subscribe to any server's member-update topic by sending a Subscribe message with an arbitrary server ID, receiving live UserUpdate events including display names, avatars, and status changes for members they should not have access to.
CVE-2026-73059 1 Stoatchat 1 Stoatchat 2026-08-16 6.5 Medium
stoatchat before 0.15.0 contains a permission bypass vulnerability in the message_fetch route that checks only ViewChannel permission instead of requiring ReadMessageHistory. Attackers with ViewChannel access but ReadMessageHistory denied can retrieve individual message content by ID, bypassing the intended history restriction enforced by bulk read routes.
CVE-2025-71377 1 Stoatchat 1 Stoatchat 2026-07-23 N/A
stoatchat (delta) versions before 20250210-1 (0.8.2) contain a logic error in the query messages route. When fetching messages 'nearby' another message, the database query can be given a message limit of zero, which the database interprets as 'no limit'. A remote unauthenticated attacker can craft nearby message fetch requests to download an entire channel's message history in a single expensive request, and can send many such requests in parallel, resulting in denial of service through resource exhaustion.
CVE-2025-71388 1 Stoatchat 1 Stoatchat 2026-07-23 N/A
stoatchat (delta/Revolt) versions from 20241213-1 before 20250210-1 allow users with only ViewChannel (read) permission on a channel to fetch that channel's webhooks, including their tokens, because the webhook fetch endpoint checked for ViewChannel instead of ManageWebhooks. Using a retrieved token, an attacker can send arbitrary messages to the channel, bypassing channel permissions and impersonating a bot or webhook. Fixed in 20250210-1 (0.8.2).
CVE-2026-63306 1 Stoatchat 1 Stoatchat 2026-07-23 8.6 High
stoatchat before 0.13.5 contains an unauthenticated server-side request forgery vulnerability in the /proxy and /embed endpoints that accept arbitrary URLs without DNS resolution filtering or private IP range validation. Attackers can enumerate internal services, fingerprint applications, and reach instance metadata endpoints by supplying malicious URLs or leveraging redirect chains to access internal infrastructure.
CVE-2024-58360 1 Stoatchat 1 Stoatchat 2026-07-23 6.5 Medium
stoatchat versions before 0.7.8 fail to enforce account creation restrictions including invite-only mode, email verification, captcha, and shield verification. Attackers can create unlimited accounts with unverified email addresses, increasing denial-of-service risk and compromising service integrity.
CVE-2026-63088 1 Stoatchat 1 Stoatchat 2026-07-23 8.6 High
stoatchat before 0.14.0 contains a server-side request forgery (SSRF) vulnerability that allows unauthenticated network-accessible attackers to bypass the DNS-based IP blocklist by exploiting incomplete address validation in the url_is_blacklisted function, which inspects only the first resolved address while the underlying HTTP client iterates all cached addresses.
