Description

Worker process denial of service through file read operation. .A vulnerability exists in the Master's “pub_ret” method which is exposed to all minions. The un-sanitized input value “jid” is used to construct a path which is then opened for reading. An attacker could exploit this vulnerabilities by attempting to read from a filename that will not return any data, e.g. by targeting a pipe node on the proc file system.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for salt, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update salt to 3007.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-22242 is resolved across your whole dependency graph.

  3. Workarounds

    Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.
