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-2026-8670/ (Markdown: https://insights.sbomify.com/CVE-2026-8670/index.md)","id":"CVE-2026-8670","markdown":"https://insights.sbomify.com/CVE-2026-8670/index.md","name":"CVE-2026-8670","record":{"aliases":["GHSA-rvw7-wx4g-rq78"],"analysis":null,"analysis_generated_by":null,"assigner":"NCSC.ch","cpe":[{"product":"avantra","vendor":"avantra"}],"cvss":{"score":9.6,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-613","name":"DEPRECATED: Insufficient Session Expiration"}],"description":"Insufficient session expiration vulnerability in syslink software AG Avantra on Linux, Windows allows Reusing Session IDs (aka Session Replay).\n\nThis issue affects Avantra: before 25.3.1.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Insecure session handling on metrics web server","id":"CVE-2026-8670","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Log Files contain encrypted secrets","id":"CVE-2026-8671"},"packages":[],"prev":{"headline":"Imager versions through 1.030 for Perl allow a heap out of bounds (OOB) write on crafted multi-frame GIF files","id":"CVE-2026-8669"},"products":["Avantra"],"published":"2026-05-22","related":[{"cvss_score":7.5,"headline":"Log Files contain encrypted secrets","id":"CVE-2026-8671","kev_date_added":null,"published":"2026-05-22"},{"cvss_score":5.9,"headline":"Password re-initialization mechanism sends passwords in plain text","id":"CVE-2026-8673","kev_date_added":null,"published":"2026-05-22"},{"cvss_score":5.1,"headline":"Default credentials for internal DB","id":"CVE-2026-8672","kev_date_added":null,"published":"2026-05-22"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-05-22","vendors":["syslink software AG"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-8670/"}
