CVE-2026-47192 is a low-severity vulnerability in the Siemens kas tool versions 4.8 up to but not including 5.3. The flaw involves improper verification of cryptographic signatures, where kas processes repository configurations before validating their signatures. Under specific conditions involving repository control by an attacker and certain configuration settings, an attacker could replace a referenced repository with a malicious one. Patches addressing this issue were released in kas version 5.3. A recommended workaround is to pin the expected signature key via its fingerprint when storing it as a file in a repository.

CVE-2026-47191 is a low severity vulnerability in Siemens kas, a setup tool for bitbake-based projects. Prior to version 5.3, kas relied solely on git commit IDs (SHA-1 or SHA-256) to verify repository integrity, which could be bypassed if an attacker took over the repository and created a branch with the same name. This flaw allows users to be tricked into checking out malicious code. The issue primarily affects SHA-256 commit IDs due to the possibility of branch takeover and SHA-1 due to hash collisions. Version 5.3 addresses this vulnerability. Workarounds include avoiding sole reliance on commit IDs, validating cryptographically signed commits or tags, or using mirrored repositories with verified integrity.
