CVE-2026-90999
CriticalCVSS 9.8Summary
A multi-stage trust-boundary violation in Sentry Seer allows unauthenticated attacker-controlled telemetry to become code executed by an agent in a privileged automation environment. An external attacker can submit fabricated Sentry events without access to the victim's Sentry account, source repository, or infrastructure.
Risk Assessment
An attacker can execute arbitrary code in a privileged environment, potentially leading to compromise of automation systems and access to sensitive data.
Recommendation
Restrict telemetry sources and validate input data to prevent unauthorized event submissions. Also, regularly update Sentry Seer and apply available security patches.

WACRM 0.7.0 and earlier has vulnerabilities: row-level security policies allow authenticated users to modify their own role and account ID, enabling privilege escalation and cross-tenant movement. Additionally, match_ai_knowledge_fts and match_ai_knowledge_semantic run as SECURITY DEFINER with no account membership check, allowing non-members to read another tenant's knowledge chunks.

libheif from 1.22.0 to 1.23.2 has a heap out-of-bounds write vulnerability. Crafted HEIF/HEIC/AVIF files with nested iden/auxl references cause duplicate Alpha planes with different bit depths, and scale_nearest_neighbor() allocates a buffer based on the first plane's 8-bit depth, leading to an overflow.

kcp before 0.31.4 and 0.32.2 fails to strip inbound identity headers (X-Remote-User, X-Remote-Group, X-Remote-Extra-*) before forwarding requests to shards. Any authenticated tenant can inject X-Remote-Group: system:masters, gaining full privileges.

IBM Common Licensing Agent 9.0 and ART 9.0 (including subversions) are vulnerable to cross-site request forgery, allowing an attacker to execute malicious actions from a user that the website trusts.
Original NVD description (English source)
Sentry Seer is vulnerable to a multi-stage trust-boundary violation that allows unauthenticated attacker-controlled telemetry to become code that is executed by an agent in a privileged automation environment. An external attacker can submit fabricated Sentry events without having access to the victim’s Sentry account, source repository, or infrastructure.
