Vulnerability description
DayBreach CVE AI Research
CVE-2026-105628 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.
Plane is an open-source project management tool. 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.
