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-2026-93748 in the wild and no public exploit code.\n\nAffected product: kornelski http-cache-semantics. 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-2026-93748/ (Markdown: https://insights.sbomify.com/CVE-2026-93748/index.md)","id":"CVE-2026-93748","markdown":"https://insights.sbomify.com/CVE-2026-93748/index.md","name":"CVE-2026-93748","record":{"aliases":["AZL-103448","AZL-103485","CLEANSTART-2026-JV93076","CLEANSTART-2026-UD09279","CLEANSTART-2026-YQ53384","CLSA-2026-1792231034","CLSA-2026-1792743662","DEBIAN-CVE-2026-93748","MINI-37j4-8687-3cjv","MINI-3wcg-grvj-jc7p","MINI-6jcq-7j23-mvrw","MINI-7hph-83vp-9q46","MINI-7w6p-f4vp-447v","MINI-85g7-pv4f-qcmv","MINI-8hh7-696v-mvmp","MINI-97x4-7pfr-4qg9","MINI-9f6f-m5xm-vmx6","MINI-c2mm-x7vg-5685","MINI-fjh7-r85v-q5vp","MINI-fvh8-9jq5-2cp7","MINI-m6cm-3v9g-q33w","MINI-qf8f-gcjf-rgw9","MINI-r4j4-9pjv-q4mg","MINI-rjxq-36pf-4qjj","MINI-v95w-x6j3-36p5","MINI-wmf2-qqmv-wf9r","ROOT-APP-NPM-CVE-2026-93748","UBUNTU-CVE-2026-93748"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js caching library","requires_auth":"none","summary":"Attackers can retrieve other users' cached session cookies by exploiting improper validation of max-stale directives in the http-cache-semantics library.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-524","name":"Use of Cache Containing Sensitive Information"}],"description":"http-cache-semantics through 4.2.0 fails to properly validate security-zeroed cache entries when processing client max-stale directives, allowing unauthenticated attackers to retrieve cached responses belonging to other users.
