CVE-2026-85150

HIGH7.5

Published 2026-09-03 · Source secalert@redhat.com

Description

A NULL pointer dereference flaw was found in GStreamer's RTSP support library. The vulnerability occurs while parsing an Authorization or WWW-Authenticate header that uses Digest authentication. Specially crafted whitespace placement around a parameter's terminator can cause an internal length calculation to underflow, leading to a crash of the process parsing the header. On an RTSP server this can be triggered by a remote, unauthenticated attacker sending a single malformed request when the server has authentication enabled; the same flaw can also be triggered against an RTSP client by a malicious or compromised RTSP server. Successful exploitation results in a denial of service (application crash) and has no confirmed impact on confidentiality or integrity.

CVE-2025-12737
The administrative operations within the Carbon Console do not adequately validate specific user-supplied input. This oversight allows a malicious actor with administrative privileges to inject and execute arbitrary code remotely. Successful exploitation enables a threat actor with administrative privileges and Carbon Console access to execute remote arbitrary code through specific administrative operations, leading to a complete compromise of the affected system.

CVE-2026-85175
SiYuan versions <= 3.8.1 (fixed in v3.8.2) contain an incomplete blocklist in the IsForbiddenAbsPath() function (kernel/util/path_guard.go), which only blocks conf/conf.json by exact match and does not restrict the TLS private key (conf/key.pem) or CA private key (conf/ca.key) stored in the same conf/ directory. Because the getFile handler skips the blocklist for RoleAdministrator and all authenticated users receive RoleAdministrator in v3.8.1, any user (or any client on a default no-auth-code instance) can retrieve these private keys via POST /api/file/getFile. On deployments with TLS enabled, this allows decryption of captured HTTPS traffic (key.pem) and forging of certificates trusted by clients that imported SiYuan's CA (ca.key).

CVE-2026-85174
SiYuan before v3.8.2 logs API tokens from query parameters in plaintext to an accessible log file when full-text search requests exceed timing thresholds. Authenticated attackers can read the log file via the getFile endpoint to recover admin API tokens and gain permanent administrative access.

CVE-2026-85164
WWBN AVideo through commit c91b5975d contains a server-side request forgery vulnerability in the set_api_userImages API endpoint that fails to validate profileImg and backgroundImg URLs before fetching them. Authenticated API clients can supply internal URLs to fetch cloud metadata or internal services, with responses written to publicly accessible web paths for retrieval.
