An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-55742 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- cotonti/cotonti (Packagist): affected all versions up to 1.0.0; no fix listed\n- cotonti/cotonti (Packagist): affected all versions up to 1.0.0; 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-2026-55742/ (Markdown: https://insights.sbomify.com/CVE-2026-55742/index.md)","id":"CVE-2026-55742","markdown":"https://insights.sbomify.com/CVE-2026-55742/index.md","name":"CVE-2026-55742","record":{"aliases":["GHSA-7g3p-35vc-mgjr"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Cotonti CMS","requires_auth":"none","summary":"Attackers can force admins to change group access rights via CSRF, leading to privilege escalation in Cotonti CMS.","user_interaction":"required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TuranSec","cpe":[],"cvss":{"score":9.4,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"Cotonti 1.0.0 (master branch, commit f43f1fc3) is vulnerable to Cross-Site Request Forgery in the administration rights handler.
