While the application's request-handling middleware includes standard panic recovery, internal background processes were previously exposed. If an attacker identifies a condition that triggers a panic within these worker functions, the resulting uncaught exception causes the entire server process to crash, leading to a denial-of-service (DoS) condition. This issue was addressed by introducing a routine.SafeWrap(f) helper function across all internal worker processes to intercept and recover from panics, converting them into manageable errors. The vulnerability is tracked as CVE-2026-82410 and affects multiple version branches. Administrators are urged to update to the latest patched releases to restore process stability.

Impact

Successful exploitation results in a persistent denial-of-service, as the entire PocketBase server process terminates upon the occurrence of a triggered panic. This impacts availability for all services hosted on the instance. The issue affects users running versions prior to v0.22.48 and versions between v0.23.0 and v0.39.7.

Recommendation

Prioritized actions for administrators:

  • Patch PocketBase to version v0.39.7 or v0.22.48 immediately to integrate the routine.SafeWrap error handling for all worker goroutines.
  • Audit server logs for unexpected process crashes or Go runtime panic stacks that coincide with specific user-initiated API requests or background tasks.
  • Monitor service availability metrics for frequent restarts of the PocketBase process, which may indicate an ongoing attempt to exploit CVE-2026-82410.
