RARLAB - UnRAR · Listed in the CISA KEV since 2022-08-09. This indicates confirmed attacks in production environments.
Required action: Apply updates per vendor instructions.
CVE-2022-30333
HighCVSS 7.5KEVExploitation Probability (EPSS)
Very high risk100th percentile - higher than 100% of all known CVEs
Summary
RARLAB UnRAR before 6.12 on Linux and UNIX allows directory traversal to write to files during an extract (aka unpack) operation, as demonstrated by creating a ~/.ssh/authorized_keys file. NOTE: WinRAR and Android RAR are unaffected.
Risk Assessment
An attacker can exploit the vulnerability to overwrite user files, potentially leading to unauthorized system access (e.g., via SSH keys).
Recommendation
Update UnRAR to version 6.12 or later and be cautious when extracting archives from untrusted sources.

- CVE-2026-95860Critical
In node-opcua (an OPC UA implementation for TypeScript and Node.js), versions 2.42.0 through 2.180.0 do not honor namespace-level access control configured via setDefaultRolePermissions for nodes without explicit per-node permissions. SessionContext.getApplicableRolePermissions reads a missing or null value instead of the configured namespace field, and the null result is treated permissively. As a result, an anonymous network client can write variables or call bound methods when an operator relied on restrictive namespace defaults.
