An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-107826 exists.\n\nAffected packages and fixed versions:\n- github.com/corazawaf/coraza/v3 (Go): affected from 3.0.0; fixed in 3.8.1\n- github.com/corazawaf/coraza/v3 (Go): affected from 3.0.0; fixed in 3.8.1\n- github.com/corazawaf/coraza/v3 (Go): affected from 3.0.0; fixed in 3.8.1\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-2026-107826/ (Markdown: https://insights.sbomify.com/CVE-2026-107826/index.md)","id":"CVE-2026-107826","markdown":"https://insights.sbomify.com/CVE-2026-107826/index.md","name":"CVE-2026-107826","record":{"aliases":["GHSA-6gcq-wc29-5xf2","GO-2026-6693"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Go WAF library","requires_auth":"none","summary":"An unauthenticated attacker can crash the hosting process by submitting deeply nested JSON that bypasses depth limits in the Coraza WAF library.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-674","name":"Uncontrolled Recursion"}],"description":"OWASP Coraza WAF is a golang modsecurity compatible web application firewall library. From 3.0.0 until 3.8.1, readJSON in internal/bodyprocessors/json.go can stop its bounded flattening walk after reaching SecArgumentsLimit or the byte budget and then call gjson.Valid on the complete raw body. An unauthenticated attacker can submit shallow values followed by an extremely deeply nested JSON tail that was not visited by the bounded walk, causing gjson.Valid to recurse without a depth bound and terminate the hosting process with an unrecoverable fatal stack overflow. The ProcessRequest and ProcessResponse JSON paths share the affected readJSON validation flow, and the payload can remain within recommended body-size and argument-count limits.
