CVE-2026-93851Mattermost versions 11.9.x <= 11.9.1, 11.8.x <= 11.8.5, 11.7.x <= 11.7.10 fail to validate the target post ID in the Agents plugin's mention reminder component, which allows an authenticated user who can post in a channel visible to a system administrator to cause the administrator's browser to send an unintended API request, resulting in replacement of an installed plugin and code execution on the server, via a crafted post containing a forged mention reminder that the administrator clicks.

CVE-2026-61572AVideo is a video-sharing Platform. Before the initial remediation attempt in 8.1.0, `url_get_contents` in `objects/functions.php` accepts caller-controlled destinations after only `FILTER_VALIDATE_URL` syntax validation, without rejecting private, loopback, or link-local addresses, and disables TLS peer verification. `Login::isLogged` reauthenticates using the attacker-settable `encoder_aVideoURL` cookie together with arbitrary nonempty `encoder_user` and `encoder_pass` cookies, and `Login::run` stores the raw fetched body in `result`. The unauthenticated `objects/login.json.php` endpoint returns that session object, enabling full-response exfiltration through a supplied `siteURL`; its `Streamer::isURLAllowed` gate allows all sites when the operator allowlist is empty, the default. An unauthenticated remote attacker can read internal HTTP and HTTPS responses, including cloud instance-metadata credentials, and reach internal TCP services. A further pre-authentication FTP variant in `view/youtubeDl.json.php` routes an ftp `videoURL` into `FTPDownloader`; `parseFtpUrl` in `objects/FTPDownloader.php` accepts its host and port for `ftp_connect`. This also enables requests to internal FTP services. Untrusted self-signed HTTPS certificates are accepted, and no account or operator interaction is required. Version 8.1.0 contains an initial remediation attempt that removes raw-response reflection and adds destination checks, but private-network exemptions and login TLS-verification defaults leave complete remediation of the described internal-network and TLS variants unresolved.

CVE-2026-61571AVideo is a video-sharing Platform. Prior to 8.1.0, the encoder lacks a global authentication layer and exposes control and status PHP endpoints to anonymous network callers. `view/run.php` has a commented-out guard and invokes `Encoder::run()`. `view/queue.json.php` calls `Encoder::getAll(true)`, reveals streamer URLs through `getSiteURL()`, and triggers processing with `execRun()`. `view/status.php` returns `Access-Control-Allow-Origin` with a wildcard, reads the queue, triggers processing, and exposes host memory statistics through `ServerMonitor::getMemory()` when `serverStatus` is set. `view/listFiles.json.php` checks only `Login::canBulkEncode()`, which admits anonymous callers whenever `disableBulkEncode` is empty, the default. Its `path` parameter is resolved with `realpath()` and listed with `scandir()` without a base-directory restriction. An unauthenticated attacker can drive the privileged queue processor, read queue and streamer-site information, obtain memory statistics and enumerate media file names and paths in any directory readable by the web-server user. Enumeration is limited to configured media extensions and does not itself disclose arbitrary file contents. This issue is fixed in version 8.1.0.

CVE-2026-61569AVideo is a video-sharing Platform. Prior to 8.1.0, the unauthenticated streamer login at `objects/login.json.php` passes the `user` parameter to `Streamer::get` in `objects/Streamer.php`, where it is interpolated into a single-quoted MariaDB SELECT without parameterization or escaping. Although `objects/security.php` strips literal single quotes, `html_entity_decode` in `objects/Login.php` restores entity-encoded quotes before the query. The supplied `siteURL` must pass the streamer allowlist, which allows all sites when empty by default, and an attacker-hosted login response must set `canUpload` or `isAdmin` to reach `Streamer::createIfNotExists`. That function calls `Streamer::get` before its additional allowlist check. UNION results are exposed through `streamers_id`, while failures return the rendered query and MariaDB error. An attacker can read arbitrary encoder database data, including stored upstream streamer credentials, allowlist configuration, and queue records, without encoder credentials. Stacked statements are not permitted by the mysqli driver and the tested database account lacks global FILE privilege, so the demonstrated vector is bounded to reads rather than server-side file writes. Stolen streamer credentials can provide continued upstream access until rotated. This issue is fixed in version 8.1.0.

CVE-2026-54453OpenCATS is an open-source applicant tracking system and recruitment CRM for staffing agencies and hiring teams. Prior to version 0.10.0, the Professional License configuration feature in `SettingsUI` (`manageProfessional`) accepts administrator-controlled license key input that is reconstructed into a PHP `define()` statement in `config.php` without safe escaping. Because the application includes `config.php`, crafted input can alter the file's PHP syntax and cause persistent arbitrary PHP execution with the web server process privileges. An authenticated administrator must have Settings module access and permission to update Professional License configuration, and `config.php` must be writable for this write-based path. Successful exploitation can read, modify or delete application data, expose candidate, contact, company, job order and user account information, alter the installation or configuration, and provide a foothold for further attacks. Unauthenticated exploitation and exploitation without Settings access are not established. This issue is fixed in version 0.10.0.
