{"apiVersion":"1.0","identifier":"CVE-2026-47191","description":"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.","publishedAt":"2026-08-14T17:18:15","lastModifiedAt":"2026-08-18T02:17:26","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-47191","cvssScore":2.1,"cvssVector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:P/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","epssProbability":0.00159,"riskScore":0.21,"affectedProduct":"kas","affectedVersions":"<5.3","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-47191","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-47191","en":"https://www.redsauce.net/en/cves/CVE-2026-47191","fr":"https://www.redsauce.net/fr/cves/CVE-2026-47191","pt":"https://www.redsauce.net/pt/cves/CVE-2026-47191","de":"https://www.redsauce.net/de/cves/CVE-2026-47191","sk":"https://www.redsauce.net/sk/cves/CVE-2026-47191","el":"https://www.redsauce.net/el/cves/CVE-2026-47191"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-47191"}}
