Prior to 1.4.0, Plane's OAuth avatar synchronization flow fetches avatar_url from provider user data through a server-side HTTP request without internal IP validation and follows redirects by default. An attacker can provide an avatar URL that redirects to an internal-only resource, such as a metadata endpoint, and Plane uploads the fetched response as a user avatar file. The object is then exposed through /api/assets/v2/static/{asset_id}/, allowing exfiltration of internally fetched content. This issue is fixed in 1.4.0."}],"source":{"advisory":"GHSA-cv9p-325g-wmv5","discovery":"UNKNOWN"}},"adp":[{"references":[{"url":"https://github.com/makeplane/plane/security/advisories/GHSA-cv9p-325g-wmv5","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-10-05T17:56:44.537944Z","id":"CVE-2026-105628","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-10-05T17:57:41.515Z"}}]}}
