CVE-2026-62900Network attack vector

Credential disclosure via embedded repository URLs

Published Aug 11, 2026 · Updated Aug 25, 2026

Information disclosure in Microsoft .NET before 8.0.30, 9.0.19, and 10.0.11 allows remote attackers to read embedded credentials over a network. In Microsoft.Build.Tasks.Git, the GitOperations.GetRepositoryUrl path preserves credentials in git remote URLs, and Source Link can write those unsanitized URLs into assembly metadata and PDB content used by Microsoft.SourceLink.AzureRepos.Git. Exposure requires builds or packages produced from repository URLs that include credentials, so the consequence is disclosure from shipped binaries or symbols rather than code execution or data tampering.
