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-2025-3757 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/openpubkey/openpubkey (Go): affected all versions; fixed in 0.10.0\n- github.com/openpubkey/openpubkey (Go): affected all versions; fixed in 0.10.0\n- github.com/openpubkey/openpubkey (Go): affected all versions; fixed in 0.10.0\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-2025-3757/ (Markdown: https://insights.sbomify.com/CVE-2025-3757/index.md)","id":"CVE-2025-3757","markdown":"https://insights.sbomify.com/CVE-2025-3757/index.md","name":"CVE-2025-3757","record":{"aliases":["DEBIAN-CVE-2025-3757","GHSA-537f-gxgm-3jjq","GO-2025-3679","UBUNTU-CVE-2025-3757"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenPubKey Go library","requires_auth":"none","summary":"A specially crafted JWS can bypass signature verification in the OpenPubKey library, allowing attackers to circumvent authentication mechanisms.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cloudflare","cpe":[{"product":"openpubkey","vendor":"openpubkey"}],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:L/SC:L/SI:L/SA:L/AU:Y","version":"4.0"},"cwes":[{"id":"CWE-347","name":"Improper Verification of Cryptographic Signature"},{"id":"CWE-305","name":"Authentication Bypass by Primary Weakness"}],"description":"Versions of OpenPubkey library prior to 0.10.0  contained a vulnerability that would allow a specially crafted JWS to bypass signature verification.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Authentication Bypass in OpenPubKey","id":"CVE-2025-3757","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"auth_bypass","year":"2025"},"n_packages":3,"n_references":1,"next":{"headline":"Exposure of Device Configuration without Authentication in WF2220","id":"CVE-2025-3758"},"packages":[{"ecosystem":"Go","fixed":["0.10.0"],"introduced":["0"],"last_affected":[],"package":"github.com/openpubkey/openpubkey","purl":null,"source":"GHSA-537f-gxgm-3jjq"},{"ecosystem":"Go","fixed":["0.10.0"],"introduced":["0"],"last_affected":[],"package":"github.com/openpubkey/openpubkey","purl":"pkg:golang/github.com/openpubkey/openpubkey","source":"GHSA-537f-gxgm-3jjq"},{"ecosystem":"Go","fixed":["0.10.0"],"introduced":["0"],"last_affected":[],"package":"github.com/openpubkey/openpubkey","purl":"pkg:golang/github.com/openpubkey/openpubkey","source":"GO-2025-3679"}],"prev":{"headline":"Denial of Service Vulnerabilities in System 800xA, Symphony® Plus IEC 61850","id":"CVE-2025-3756"},"products":["OPKSSH"],"published":"2025-05-13","related":[{"cvss_score":9.3,"headline":"Authentication Bypass in OPKSSH","id":"CVE-2025-4658","kev_date_added":null,"published":"2025-05-13"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"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":"2025-05-13","vendors":["OPKSSH"]},"summary":"A specially crafted JWS can bypass signature verification in the OpenPubKey library, allowing attackers to circumvent authentication mechanisms.","url":"https://insights.sbomify.com/CVE-2025-3757/"}
