{"answers":{"affected":"3 open source packages ship an affected version, including github.com/refraction-networking/utls.","exploited":"There is no known exploitation of CVE-2026-26995 in the wild and no public exploit code.","fix":"Upgrade github.com/refraction-networking/utls to 1.8.2 or later.","what":"CVE-2026-26995 is a vulnerability in github.com/refraction-networking/utls."},"fix_prompt":"Check this codebase for CVE-2026-26995 and fix it if it is affected.\n\nWhat it is: CVE-2026-26995 is a vulnerability in github.com/refraction-networking/utls. \nExploitation: There is no known exploitation of CVE-2026-26995 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/refraction-networking/utls (Go): affected from 1.6.0; fixed in 1.8.2\n- github.com/refraction-networking/utls (Go): affected from 1.6.0; fixed in 1.8.2\n- github.com/refraction-networking/utls (Go): affected from 1.6.0; fixed in 1.8.2\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-2026-26995/ (Markdown: https://insights.sbomify.com/CVE-2026-26995/index.md)","id":"CVE-2026-26995","markdown":"https://insights.sbomify.com/CVE-2026-26995/index.md","name":"CVE-2026-26995","record":{"aliases":["GHSA-rrxv-pmq9-x67r","GO-2026-4512"],"analysis":null,"analysis_generated_by":null,"assigner":"GitHub_M","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"Further research determined the issue is an external dependency vulnerability.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"uTLS has a fingerprint vulnerability from missing padding extension for Chrome 120","id":"CVE-2026-26995","indexable":false,"kev":null,"kind":"cve_rejected","links":{"ecosystem":"Go","product":null,"products":[],"type":null,"year":"2026"},"n_packages":3,"n_references":0,"next":{"headline":"minimatch has a ReDoS via repeated wildcards with non-matching literal in pattern","id":"CVE-2026-26996"},"packages":[{"ecosystem":"Go","fixed":["1.8.2"],"introduced":["1.6.0"],"last_affected":[],"package":"github.com/refraction-networking/utls","purl":null,"source":"GHSA-rrxv-pmq9-x67r"},{"ecosystem":"Go","fixed":["1.8.2"],"introduced":["1.6.0"],"last_affected":[],"package":"github.com/refraction-networking/utls","purl":"pkg:golang/github.com/refraction-networking/utls","source":"GHSA-rrxv-pmq9-x67r"},{"ecosystem":"Go","fixed":["1.8.2"],"introduced":["1.6.0"],"last_affected":[],"package":"github.com/refraction-networking/utls","purl":"pkg:golang/github.com/refraction-networking/utls","source":"GO-2026-4512"}],"prev":{"headline":"uTLS ServerHellos are accepted without checking TLS 1.3 downgrade canaries","id":"CVE-2026-26994"},"products":[],"published":null,"related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"REJECTED","updated":"2026-02-20","vendors":[]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-26995/"}
