An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-33620 exists.\n\nAffected packages and fixed versions:\n- github.com/pinchtab/pinchtab (Go): affected from 0.7.8; fixed in 0.8.4\n- github.com/pinchtab/pinchtab (Go): affected from 0.7.8; fixed in 0.8.4\n- github.com/pinchtab/pinchtab (Go): affected from 0.7.8; fixed in 0.8.4\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-2026-33620/ (Markdown: https://insights.sbomify.com/CVE-2026-33620/index.md)","id":"CVE-2026-33620","markdown":"https://insights.sbomify.com/CVE-2026-33620/index.md","name":"CVE-2026-33620","record":{"aliases":["GHSA-mrqc-3276-74f8","GO-2026-4822"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"AI browser control server","requires_auth":"none","summary":"Attackers can steal API tokens exposed in URLs via logs or intermediaries, potentially gaining unauthorized control over the AI browser server.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"pinchtab","vendor":"pinchtab"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-598","name":"Use of HTTP Request With Sensitive Query String"}],"description":"PinchTab is a standalone HTTP server that gives AI agents direct control over a Chrome browser. PinchTab `v0.7.8` through `v0.8.3` accepted the API token from a `token` URL query parameter in addition to the `Authorization` header. When a valid API credential is sent in the URL, it can be exposed through request URIs recorded by intermediaries or client-side tooling, such as reverse proxy access logs, browser history, shell history, clipboard history, and tracing systems that capture full URLs. This issue is an unsafe credential transport pattern rather than a direct authentication bypass. It only affects deployments where a token is configured and a client actually uses the query-parameter form. PinchTab's security guidance already recommended `Authorization: Bearer \u003ctoken\u003e`, but `v0.8.3` still accepted `?token=` and included first-party flows that generated and consumed URLs containing the token. This was addressed in v0.8.4 by removing query-string token authentication and requiring safer header- or session-based authentication flows.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"PinchTab: API Bearer Token Exposed in URL Query Parameter via Server Logs and Intermediary Systems","id":"CVE-2026-33620","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":3,"n_references":2,"next":{"headline":"PinchTab: Unapplied Rate Limiting Middleware Allows Unbounded Brute-Force of API Token","id":"CVE-2026-33621"},"packages":[{"ecosystem":"Go","fixed":["0.8.4"],"introduced":["0.7.8"],"last_affected":[],"package":"github.com/pinchtab/pinchtab","purl":null,"source":"GHSA-mrqc-3276-74f8"},{"ecosystem":"Go","fixed":["0.8.4"],"introduced":["0.7.8"],"last_affected":[],"package":"github.com/pinchtab/pinchtab","purl":"pkg:golang/github.com/pinchtab/pinchtab","source":"GHSA-mrqc-3276-74f8"},{"ecosystem":"Go","fixed":["0.8.4"],"introduced":["0.7.8"],"last_affected":[],"package":"github.com/pinchtab/pinchtab","purl":"pkg:golang/github.com/pinchtab/pinchtab","source":"GO-2026-4822"}],"prev":{"headline":"PinchTab has Unauthenticated Blind SSRF in Task Scheduler via Unvalidated callbackUrl","id":"CVE-2026-33619"},"products":["pinchtab"],"published":"2026-03-26","related":[{"cvss_score":7.5,"headline":"PinchTab: SSRF with Full Response Exfiltration via Download Handler","id":"CVE-2026-30834","kev_date_added":null,"published":"2026-03-07"},{"cvss_score":6.7,"headline":"PinchTab: OS Command Injection via Profile Name in Windows Cleanup Routine Enables Arbitrary Command Execution","id":"CVE-2026-33623","kev_date_added":null,"published":"2026-03-26"},{"cvss_score":6.1,"headline":"A PinchTab Security Policy Bypass in /wait Allows Arbitrary JavaScript Execution","id":"CVE-2026-33622","kev_date_added":null,"published":"2026-03-26"},{"cvss_score":5.8,"headline":"PinchTab has Blind SSRF via browser-side redirect bypass in /download URL validation","id":"CVE-2026-33081","kev_date_added":null,"published":"2026-03-20"},{"cvss_score":4.8,"headline":"PinchTab: Unapplied Rate Limiting Middleware Allows Unbounded Brute-Force of API Token","id":"CVE-2026-33621","kev_date_added":null,"published":"2026-03-26"},{"cvss_score":4.1,"headline":"PinchTab has Unauthenticated Blind SSRF in Task Scheduler via Unvalidated callbackUrl","id":"CVE-2026-33619","kev_date_added":null,"published":"2026-03-26"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"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":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-03-30","vendors":["pinchtab"]},"summary":"Attackers can steal API tokens exposed in URLs via logs or intermediaries, potentially gaining unauthorized control over the AI browser server.","url":"https://insights.sbomify.com/CVE-2026-33620/"}
