CVE-2023-38065Network attack vector

Script execution via stored build-log content

Published Jul 12, 2023 · Updated Oct 22, 2024

Stored cross-site scripting in JetBrains TeamCity before 2023.05.1 allows remote authenticated users to execute script through build logs. JetBrains identifies build-log viewing as the execution locus but has not disclosed which log-producing path stores attacker-controlled content without safe output encoding. Exploitation requires a user to view the affected log, and the resulting code runs only in that viewer's browser context.
