CVE-2024-39458Network attack vector

Secret disclosure via unmasked diagnostic arguments

Published Jun 26, 2024 · Updated Feb 13, 2025

Information disclosure in Jenkins Structs Plugin 337.v1b_04ea_4df7c8 and earlier allows attackers to read secrets from the system log. DescribableModel exception paths concatenate complete argument maps into warning text, while UninstantiatedDescribable renders Secret values directly instead of masking them. Exposure requires a failed build-step configuration containing a Secret parameter, and the disclosed value becomes available to readers of the default system log.
