Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-25898 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- jsrsasign (npm): affected from 4.8.0; fixed in 10.5.25\n- jsrsasign (npm): affected from 4.8.0; fixed in 10.5.25\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-2022-25898/ (Markdown: https://insights.sbomify.com/CVE-2022-25898/index.md)","id":"CVE-2022-25898","markdown":"https://insights.sbomify.com/CVE-2022-25898/index.md","name":"CVE-2022-25898","record":{"aliases":["GHSA-3fvg-4v2m-98jf"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript crypto library","requires_auth":"low_privilege","summary":"Attackers can bypass JWS or JWT signature verification using specially crafted non-Base64URL characters, allowing unauthorized access.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"snyk","cpe":[{"product":"jsrsasign","vendor":"kjur"}],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:L/I:L/A:H/E:P","version":"3.1"},"cwes":[{"id":"CWE-347","name":"Improper Verification of Cryptographic Signature"}],"description":"The package jsrsasign before 10.5.25 are vulnerable to Improper Verification of Cryptographic Signature when JWS or JWT signature with non Base64URL encoding special characters or number escaped characters may be validated as valid by mistake.
