EchelonGraph scoreLOW confidence

This medium-severity CVE scores 4.2 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Obot 0.25.0 before 0.25.6 and 0.26.0 before 0.26.1 contains a race condition in auth provider group refreshes that can restore group memberships just revoked in the identity provider. When overlapping refreshes for the same user commit out of order, stale memberships are persisted and the user retains revoked group-based access for about ten minutes.

Exploitation none (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.
