      <title>CVE-2026-47191 — kas checks out SHA-like git branches as valid commits</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2026-47191</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; siemens kas&lt;/p&gt;
&lt;p&gt;kas is a setup tool for bitbake based projects. Prior to version 5.3, when relying solely on a git commit ID (SHA-1 or SHA-256) to qualify if a checkout of a repository is equivalent to the state validated while adding its commit ID to a kas configuration, users may be tricked to check out a branch of the same name from this repository. This implies that the referenced repository has been taken over by an attacker and modified to carry such a branch. SHA-1 commits may also be replaced by creating hash collisions, so the primary impact of this issue is on SHA-256 commit IDs. Version 5.3 fixes the issue. As a workaround, avoid relying solely on the commit ID for integrity validation of a repository that might become under control of a malicious 3rd party. If available, additional validate cryptographically signed commits or tags. Alternatively, mirror the repository to a save place, validate its integrity, and use this instead of the original one.&lt;/p&gt;</description>
