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-2023-31582/ (Markdown: https://insights.sbomify.com/CVE-2023-31582/index.md)","id":"CVE-2023-31582","markdown":"https://insights.sbomify.com/CVE-2023-31582/index.md","name":"CVE-2023-31582","record":{"aliases":["DEBIAN-CVE-2023-31582","GHSA-7g24-qg88-p43q","UBUNTU-CVE-2023-31582"],"analysis":null,"analysis_generated_by":null,"assigner":"mitre","cpe":[{"product":"jose4j","vendor":"jose4j_project"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-331","name":"Insufficient Entropy"}],"description":"jose4j before v0.9.3 allows attackers to set a low iteration count of 1000 or less.","ecosystems":["Maven"],"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":"jose4j uses weak cryptographic algorithm","id":"CVE-2023-31582","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":null,"year":"2023"},"n_packages":2,"n_references":2,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2023-31584"},"packages":[{"ecosystem":"Maven","fixed":["0.9.3"],"introduced":["0"],"last_affected":[],"package":"org.bitbucket.b_c:jose4j","purl":null,"source":"GHSA-7g24-qg88-p43q"},{"ecosystem":"Maven","fixed":["0.9.3"],"introduced":["0"],"last_affected":[],"package":"org.bitbucket.b_c:jose4j","purl":"pkg:maven/org.bitbucket.b_c/jose4j","source":"GHSA-7g24-qg88-p43q"}],"prev":{"headline":"Sureness uses hardcoded key","id":"CVE-2023-31581"},"products":["n/a"],"published":"2023-10-24","related":[{"cvss_score":7.5,"headline":"jose4j is vulnerable to DoS via compressed JWE content","id":"CVE-2024-29371","kev_date_added":null,"published":"2025-12-17"},{"cvss_score":6.5,"headline":"jose4j denial of service via specifically crafted JWE","id":"CVE-2023-51775","kev_date_added":null,"published":"2023-12-25"}],"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":"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":"partial"},"state":"PUBLISHED","updated":"2024-09-11","vendors":["n/a"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2023-31582/"}
