An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-66920 in the wild and no public exploit code.\n\nAffected product: Pivotick. 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-2026-66920/ (Markdown: https://insights.sbomify.com/CVE-2026-66920/index.md)","id":"CVE-2026-66920","markdown":"https://insights.sbomify.com/CVE-2026-66920/index.md","name":"CVE-2026-66920","record":{"aliases":["GHSA-cgxr-m8cj-3q4w"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript graph library","requires_auth":"none","summary":"Attackers can cause browser crashes or freezes in Pivotick by supplying deeply nested or cyclic graph data, exhausting the JavaScript call stack.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CIRCL","cpe":[],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:H","version":"4.0"},"cwes":[{"id":"CWE-674","name":"Uncontrolled Recursion"},{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"Pivotick contains an uncontrolled-recursion vulnerability when processing caller-supplied graph and node data. The affected graph algorithms recursively traversed graph edges, while the JSON viewer recursively processed each level of a node’s data structure. A specially crafted graph containing an excessively long path, deeply nested properties, or circular object references could therefore exhaust the JavaScript call stack when Pivotick calculates a layout or displays a node in the inspection modal.\n\nSuccessful exploitation may cause an uncaught exception, freeze the affected page, or crash the browser tab, resulting in a client-side denial of service. No confidentiality or integrity impact has been identified.\n\nThe patch replaces the recursive graph traversals with iterative stack-based implementations and limits the reachability calculation to 1,000,000 edge traversals. It also limits JSON rendering to 64 levels and detects circular references before descending further into an object.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Pivotick - Stack Exhaustion Denial of Service via Deep or Cyclic Graph Data","id":"CVE-2026-66920","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Pivotick - Stored DOM-Based Cross-Site Scripting via Unescaped Markdown Node References","id":"CVE-2026-66921"},"packages":[],"prev":{"headline":"Stored DOM-Based Cross-Site Scripting in Node Modal Headers","id":"CVE-2026-66919"},"products":["Pivotick"],"published":"2026-07-28","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-07-28","vendors":["Pivotick"]},"summary":"Attackers can cause browser crashes or freezes in Pivotick by supplying deeply nested or cyclic graph data, exhausting the JavaScript call stack.","url":"https://insights.sbomify.com/CVE-2026-66920/"}
