An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-8454 in the wild and no public exploit code.\n\nAffected product: Debian devscripts. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2025-8454/ (Markdown: https://insights.sbomify.com/CVE-2025-8454/index.md)","id":"CVE-2025-8454","markdown":"https://insights.sbomify.com/CVE-2025-8454/index.md","name":"CVE-2025-8454","record":{"aliases":["DEBIAN-CVE-2025-8454","GHSA-mw9f-f52p-chpp","UBUNTU-CVE-2025-8454"],"analysis":{"component_type":"developer_tool","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Debian devscripts","requires_auth":"none","summary":"Attackers can bypass OpenPGP verification in uscan by exploiting cached downloads, allowing unverified upstream sources to be accepted.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"debian","cpe":[{"product":"devscripts","vendor":"debian"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-347","name":"Improper Verification of Cryptographic Signature"}],"description":"It was discovered that uscan, a tool to scan/watch upstream sources for new releases of software, included in devscripts (a collection of scripts to make the life of a Debian Package maintainer easier), skips OpenPGP verification if the upstream source is already downloaded from a previous run even if the verification failed back then.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Security feature bypass in devscripts","id":"CVE-2025-8454","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Reflected XSS in Kod8 Software's Kod8 Individual and SME Website","id":"CVE-2025-8456"},"packages":[],"prev":{"headline":"Privilege escalation in Saitel DP RTU","id":"CVE-2025-8453"},"products":["devscripts"],"published":"2025-08-01","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-08-01","vendors":["Debian"]},"summary":"Attackers can bypass OpenPGP verification in uscan by exploiting cached downloads, allowing unverified upstream sources to be accepted.","url":"https://insights.sbomify.com/CVE-2025-8454/"}
