CVE-2013-0865
HighSummary
Funkcja vqa_decode_chunk w libavcodec/vqavideo.c w FFmpeg przed wersją 1.0.4 oraz 1.1.x przed wersją 1.1.2 pozwala zdalnym atakującym na wywołanie nieokreślonego wpływu poprzez duży chunk cbp0 lub cbpz w pliku wideo VQA od Westwood Studios, co prowadzi do zapisu poza przydzielonym obszarem pamięci.
Risk Assessment
Atakujący mogą wykorzystać tę podatność do wprowadzenia złośliwego kodu lub destabilizacji systemu, co może prowadzić do utraty danych lub przejęcia kontroli nad systemem.
Recommendation
Zaleca się aktualizację FFmpeg do najnowszej wersji, aby usunąć tę podatność oraz monitorowanie systemów pod kątem nieautoryzowanych prób dostępu.

djust prior to version 1.0.7 has a vulnerability in the WebSocket transport that bypasses standard Django authorization mechanisms (such as LoginRequiredMixin, PermissionRequiredMixin, etc.) and the staff gate in the admin extension. Mount authorization is done via check_view_auth, not the View.dispatch() chain, allowing anonymous or under-privileged clients to open a WebSocket and dispatch view handlers, including admin ones.

UVdesk Community Skeleton through 1.1.8 fails to authenticate or validate installation state on wizard endpoints in ConfigureHelpdesk controller actions. Unauthenticated attackers can repoint the database and create super administrator accounts by submitting crafted requests to wizard endpoints, gaining full control of the instance.
- CVE-2026-92787Critical
Feast through 0.66.0 fails to verify JWT token signatures before establishing user identity, allowing attackers to bypass all role-based access control by presenting an unverified token with a hardcoded claim value. Attackers can obtain trusted internal identity and gain unchecked read and write access to all entities, feature views, data sources, and permission policies on the server.
- CVE-2026-76460CriticalActively exploited
A vulnerability in the API of Cisco Identity Services Engine (ISE) could allow an unauthenticated, remote attacker to bypass authentication. This is due to insufficient authentication control on an API endpoint. An attacker could send a crafted request to gain unauthorized access to the device by bypassing the web-based management interface.
- CVE-2026-75513Critical
Marten from version 7.0.0 until 9.13.0 has a vulnerability involving interpolation of runtime, potentially attacker-controlled strings into single-quoted SQL literals without escaping or parameterization in several LINQ and tenant-management paths. The primary confirmed vector is a dictionary indexer key used by Where filters. This could enable filter or multi-tenant authorization bypass and blind data exfiltration, and in some configurations data modification.
- CVE-2026-20332Critical
Vulnerabilities in Cisco Secure Adaptive Security Appliance Software, Cisco Secure Firewall Threat Defense Software, and Cisco Secure Firewall Management Center Software are related to improper access control issues (CWE-284). They were discovered during an internal security review and have been addressed in a software hardening release.
- CVE-2026-20284Critical
A vulnerability in the SXP REST API of Cisco ISE could allow an authenticated, remote attacker to conduct SQL injection attacks. This is due to insufficient validation of user-supplied input in REST API calls. A successful exploit could allow the attacker to view or modify data on the underlying database, and in single-node deployments could cause a DoS condition.
- CVE-2026-92808Critical
A server-side request forgery (SSRF) vulnerability exists in the UnifiedLogin service of Altium Enterprise Server. An unauthenticated network attacker can cause the server to issue outbound HTTP requests to a destination of the attacker's choosing, including internal services reachable only from the server. One such internal service exposes configuration and credential material without authentication, relying on local origin, which is satisfied by forged requests.

Original NVD description (English source)
The vqa_decode_chunk function in libavcodec/vqavideo.c in FFmpeg before 1.0.4 and 1.1.x before 1.1.2 allows remote attackers to have an unspecified impact via a large (1) cbp0 or (2) cbpz chunk in Westwood Studios VQA Video file, which triggers an out-of-bounds write.
