An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-74790 exists.\n\nAffected packages and fixed versions:\n- Scriban.Signed (NuGet): affected all versions; fixed in 7.0.0\n- Scriban.Signed (NuGet): affected all versions; fixed in 7.0.0\n- scriban (NuGet): affected all versions; fixed in 7.0.0\n- scriban (NuGet): affected all versions; fixed in 7.0.0\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-2026-74790/ (Markdown: https://insights.sbomify.com/CVE-2026-74790/index.md)","id":"CVE-2026-74790","markdown":"https://insights.sbomify.com/CVE-2026-74790/index.md","name":"CVE-2026-74790","record":{"aliases":["GHSA-5wr9-m6jw-xx44","GHSA-6w6f-93jg-2qf5"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Scriban templating library","requires_auth":"none","summary":"Attackers can bypass sandbox restrictions in Scriban by reusing cached template contexts, exposing hidden properties and fields across requests.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-693","name":"Protection Mechanism Failure"}],"description":"Scriban before 7.0.0 caches TypedObjectAccessor by Type only without considering MemberFilter changes, allowing reused TemplateContext instances to expose members that should be hidden.
