What is CVE-2024-26150?

@backstage/backend-common is a shared library used in Backstage, which is an open platform aimed at building developer portals. Prior to versions 0.21.1, 0.20.2, and 0.19.10, the library exhibited insufficient path checks through the utility resolveSafeChildPath. This inadequacy posed a risk for path traversal attacks, specifically when attackers could inject symbolic links into the system. Users of the affected versions should apply the available patches to mitigate this security issue effectively.
