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-2026-69214 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.http4s:http4s-client_2.13 (Maven): affected all versions; fixed in 0.23.35\n- org.http4s:http4s-client_2.13 (Maven): affected all versions; fixed in 0.23.35\n- org.http4s:http4s-client_2.13 (Maven): affected from 1.0.0-M1; fixed in 1.0.0-M47\n- org.http4s:http4s-client_2.13 (Maven): affected from 1.0.0-M1; fixed in 1.0.0-M47\n- org.http4s:http4s-client_2.12 (Maven): affected all versions; fixed in 0.23.35\n- org.http4s:http4s-client_2.12 (Maven): affected all versions; fixed in 0.23.35\n- org.http4s:http4s-client_3 (Maven): affected all versions; fixed in 0.23.35\n- org.http4s:http4s-client_3 (Maven): affected all versions; fixed in 0.23.35\n- org.http4s:http4s-client_3 (Maven): affected from 1.0.0-M1; fixed in 1.0.0-M47\n- org.http4s:http4s-client_3 (Maven): affected from 1.0.0-M1; fixed in 1.0.0-M47\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-2026-69214/ (Markdown: https://insights.sbomify.com/CVE-2026-69214/index.md)","id":"CVE-2026-69214","markdown":"https://insights.sbomify.com/CVE-2026-69214/index.md","name":"CVE-2026-69214","record":{"aliases":["GHSA-wv64-j4fq-5f9x"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["account_takeover","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Scala HTTP library","requires_auth":"none","summary":"A malicious server can plant cookies for other domains via Http4s CookieJar, enabling session fixation or cookie overwriting.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-565","name":"Reliance on Cookies without Validation and Integrity Checking"},{"id":"CWE-384","name":"Session Fixation"}],"description":"Http4s is a Scala interface for HTTP services. Prior to 0.23.35 and 1.0.0-M47, The CookieJar client middleware stores a response cookie’s Domain attribute without checking that it domain-matches the host that supplied the cookie or rejecting public suffixes. A malicious or compromised server contacted through the same CookieJar can plant a cookie for another domain, and the jar later sends that cookie to the victim domain, enabling session fixation or overwriting security-sensitive cookies. The patch validates the Set-Cookie domain against the response origin, although public-suffix rejection remains unimplemented.
