Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

PSI Probe package psi-probe-core, versions up to and including 5.3.0, contains a broken access control flaw in its session expiration controller that can lead to denial of service. A remote attacker can trigger it, and a public exploit exists. The source lists no fixed version, and the vendor did not respond to disclosure, so no fix is listed.

Written 2 Nov 2026.
