CVE-2026-110935 is a high-severity vulnerability rated 8.4/10 on the CVSS scale. The PFI plugin framework deployment routine does not validate path components when extracting archive entries to the local plugin repository. Archive entries containing relative path segments such as '..' are not rejected, allowing an unauthenticated local attacker to write files outside the plugin repository to arbitrary locations accessible with the current user's permissions which could result in full system compromise.. EPSS estimates a 0.20% chance of exploitation in the next 30 days.
