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-2026-41508 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/corazawaf/coraza/v3 (Go): affected from 3.4.0; fixed in 3.8.0\n- github.com/corazawaf/coraza/v3 (Go): affected from 3.4.0; fixed in 3.8.0\n- github.com/corazawaf/coraza/v3 (Go): affected from 3.4.0; fixed in 3.8.0\n- github.com/corazawaf/coraza (Go): affected all versions; no fix listed\n- github.com/corazawaf/coraza/v2 (Go): affected all versions; no fix listed\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-2026-41508/ (Markdown: https://insights.sbomify.com/CVE-2026-41508/index.md)","id":"CVE-2026-41508","markdown":"https://insights.sbomify.com/CVE-2026-41508/index.md","name":"CVE-2026-41508","record":{"aliases":["GHSA-r3rm-qphw-hh76","GO-2026-6670"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Go WAF library","requires_auth":"none","summary":"Remote attackers can bypass WAF multipart inspection rules by sending truncated bodies, allowing malicious payloads to reach backend servers.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":5.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-755","name":"Improper Handling of Exceptional Conditions"},{"id":"CWE-693","name":"Protection Mechanism Failure"}],"description":"OWASP Coraza WAF is a golang modsecurity compatible web application firewall library. From 3.4.0 until 3.8.0, the multipart processor in internal/bodyprocessors/multipart.go treats io.ErrUnexpectedEOF as nonfatal without setting MULTIPART_STRICT_ERROR. A remote attacker can submit a truncated multipart body that produces io.ErrUnexpectedEOF, causing parsing to stop without raising the strict-error signal used by the recommended defensive rule.
