Project settings modification via improper endpoint authorization
Published Jun 26, 2026 · Updated Jun 26, 2026
Improper authorization in JetBrains YouTrack before 2026.2.16593 allows remote authenticated users to modify project settings. JetBrains identifies the app configurations endpoint as the affected locus but has not disclosed which authorization check is missing or how crafted requests bypass it. Low-privileged access and a network path to the endpoint are required; successful exploitation changes project configuration without disclosing or deleting data.
