An upstream fix is merged but not yet released — mitigate (WAF / firewall / segmentation) until the release ships, then apply it.

A flaw has been found in abracadabra50 claude-sesh 1.0.0. This issue affects the function getEnrichedData/enrichSession of the file src/services/enricher.ts. Executing a manipulation of the argument sessionId can lead to path traversal. The attack needs to be launched locally. This patch is called 786c9d74800e6d0858b65778f31beb71b3983a50. Applying a patch is advised to resolve this issue.

An upstream fix is merged but not yet in a tagged release. Restrict network exposure of the affected system or apply the vendor's mitigation within your standard update timelines until it ships, then apply the release.

Exploitation public PoC (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
