It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-5479 in the wild and no public exploit code.\n\nAffected product: Wolfssl Wolfssl. 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-2026-5479/ (Markdown: https://insights.sbomify.com/CVE-2026-5479/index.md)","id":"CVE-2026-5479","markdown":"https://insights.sbomify.com/CVE-2026-5479/index.md","name":"CVE-2026-5479","record":{"aliases":["DEBIAN-CVE-2026-5479","GHSA-3xr8-r75g-g9c6","JLSEC-2026-728","UBUNTU-CVE-2026-5479"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"wolfSSL cryptographic library","requires_auth":"none","summary":"wolfSSL fails to verify ChaCha20-Poly1305 authentication tags during EVP decryption, allowing attackers to bypass integrity checks and inject tampered data.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"wolfSSL","cpe":[{"product":"wolfssl","vendor":"wolfssl"}],"cvss":{"score":7.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-354","name":"Improper Validation of Integrity Check Value"}],"description":"In wolfSSL's EVP layer, the ChaCha20-Poly1305 AEAD decryption path in wolfSSL_EVP_CipherFinal (and related EVP cipher finalization functions) fails to verify the authentication tag before returning plaintext to the caller.
