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-2026-121881/ (Markdown: https://insights.sbomify.com/CVE-2026-121881/index.md)","id":"CVE-2026-121881","markdown":"https://insights.sbomify.com/CVE-2026-121881/index.md","name":"CVE-2026-121881","record":{"aliases":["GHSA-9mg6-47p6-97j7"],"analysis":null,"analysis_generated_by":null,"assigner":"POSIT","cpe":[],"cvss":{"score":5.7,"severity":"medium","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/E:P/AU:Y/R:A/V:C/RE:M/U:Amber","version":"4.0"},"cwes":[{"id":"CWE-89","name":"Improper Neutralization of Special Elements used in an SQL Command"}],"description":"SQL injection vulnerability in the get_last_seen code-server session-state RPC in Posit Software, PBC Posit Workbench before 2026.08.0 allows authenticated users to read arbitrary data from the Workbench database via the sessionIds parameter.\n\nNOTE: exploitation requires a valid authenticated session; no administrative privileges are needed.
