An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-50549 in the wild and no public exploit code.\n\nAffected product: cursor. 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-2026-50549/ (Markdown: https://insights.sbomify.com/CVE-2026-50549/index.md)","id":"CVE-2026-50549","markdown":"https://insights.sbomify.com/CVE-2026-50549/index.md","name":"CVE-2026-50549","record":{"aliases":[],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"AI code editor","requires_auth":"none","summary":"A malicious AI agent can escape the sandbox and execute arbitrary code by exploiting symlink handling flaws during file writes.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"cursor","vendor":"anysphere"}],"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:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-59","name":"Improper Link Resolution Before File Access"}],"description":"Cursor is a code editor built for programming with AI. Prior to 3.0, Cursor runs agent terminal commands in a sandbox by default. Before a Write, the agent canonicalizes the target path to confirm it stays inside the workspace, but when canonicalization fails it falls back to the original path and writes without approval. A malicious agent can create an in-workspace symlink that points outside the workspace and force canonicalization to fail — either because the target does not exist or because read permission is removed from the path — so the agent writes through the symlink to an arbitrary location without approval. A malicious agent could write arbitrary files outside the workspace under the user's privileges. This enables non-sandboxed Remote Code Execution — for example by overwriting the cursorsandbox helper so later commands run unsandboxed — with no user interaction beyond a benign prompt. This vulnerability is fixed in 3.0.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Cursor Desktop sandbox escape via symlink and failed path canonicalization","id":"CVE-2026-50549","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Snipe-IT: 2FA reset privilege bypass","id":"CVE-2026-50550"},"packages":[],"prev":{"headline":"Cursor Desktop sandbox escape via agent-controlled working directory","id":"CVE-2026-50548"},"products":["cursor"],"published":"2026-06-25","related":[{"cvss_score":9.3,"headline":"Cursor Desktop sandbox escape via agent-controlled working directory","id":"CVE-2026-50548","kev_date_added":null,"published":"2026-06-25"},{"cvss_score":8.8,"headline":"Cursor: Speedbump Modal Bypass in MCP Server Deep-Link","id":"CVE-2025-64106","kev_date_added":null,"published":"2025-11-04"},{"cvss_score":8.8,"headline":"Cursor is Vulnerable to Path Manipulation Using Backslashes on Windows","id":"CVE-2025-64107","kev_date_added":null,"published":"2025-11-04"},{"cvss_score":8.8,"headline":"Cursor's Sensitive File Modification can Lead to NTFS Path Quirks","id":"CVE-2025-64108","kev_date_added":null,"published":"2025-11-04"},{"cvss_score":8.8,"headline":"Cursor CLI's Cursor Agent MCP OAuth2 Communication is Vulnerable to Remote Code Execution","id":"CVE-2025-61591","kev_date_added":null,"published":"2025-10-03"},{"cvss_score":8.8,"headline":"Cursor CLI: Arbitrary Code Execution Possible through Permissive CLI Config","id":"CVE-2025-61592","kev_date_added":null,"published":"2025-10-03"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-06-25","vendors":["cursor"]},"summary":"A malicious AI agent can escape the sandbox and execute arbitrary code by exploiting symlink handling flaws during file writes.","url":"https://insights.sbomify.com/CVE-2026-50549/"}
