Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-77939 exists.\n\nAffected product: flextype. 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-2026-77939/ (Markdown: https://insights.sbomify.com/CVE-2026-77939/index.md)","id":"CVE-2026-77939","markdown":"https://insights.sbomify.com/CVE-2026-77939/index.md","name":"CVE-2026-77939","record":{"aliases":["GHSA-j8rr-2wmh-q2h8"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["data_read","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Flextype CMS","requires_auth":"low_privilege","summary":"Authenticated attackers can inject expressions to read arbitrary files and potentially execute code via the query endpoint.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"},{"id":"CWE-1336","name":"Improper Neutralization of Special Elements Used in a Template Engine"}],"description":"Flextype CMS through v1.0.0-dev contains an expression language injection vulnerability that allows authenticated attackers with a valid API token to read arbitrary files by passing unsanitized user-supplied input to the Symfony ExpressionLanguage engine via the POST /api/v1/query endpoint.
