It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-90811 exists.\n\nAffected product: cosmicstack-labs mercury-agent. 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-2026-90811/ (Markdown: https://insights.sbomify.com/CVE-2026-90811/index.md)","id":"CVE-2026-90811","markdown":"https://insights.sbomify.com/CVE-2026-90811/index.md","name":"CVE-2026-90811","record":{"aliases":["GHSA-x845-4vjw-3f37"],"analysis":{"component_type":"library","fix_type":"no_fix_stated","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"mercury-agent library","requires_auth":"low_privilege","summary":"Local attackers can exploit a flaw in the Shell Permission Manifest to disclose sensitive information via the checkShellCommand function.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"},{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"A weakness has been identified in cosmicstack-labs mercury-agent up to 1.2.0.
