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-2026-77644 in the wild and no public exploit code.\n\nAffected product: PTC Windchill Risk and Reliability Enterprise Edition (Formerly Relex). 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-2026-77644/ (Markdown: https://insights.sbomify.com/CVE-2026-77644/index.md)","id":"CVE-2026-77644","markdown":"https://insights.sbomify.com/CVE-2026-77644/index.md","name":"CVE-2026-77644","record":{"aliases":["GHSA-5hvp-9mcx-5245"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Windchill Risk and Reliability","requires_auth":"none","summary":"Attackers can bypass access controls in PTC Windchill Risk and Reliability Enterprise Edition, potentially gaining unauthorized access to protected resources.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"PTC","cpe":[],"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/RE:M/U:Red","version":"4.0"},"cwes":[{"id":"CWE-620","name":"Unverified Password Change"},{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"A critical bypass access control vulnerability has been reported in PTC Windchill Risk and Reliability (WRR) Enterprise Edition.","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":"Critical Bypass Access Control Vulnerability Reported for Windchill Risk and Reliability (WRR) Enterprise Edition","id":"CVE-2026-77644","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Critical Remote Code Execution (RCE) vulnerability reported in Windchill","id":"CVE-2026-77645"},"packages":[],"prev":{"headline":"Cross-site scripting in xapian-core","id":"CVE-2026-77643"},"products":["Windchill Risk and Reliability Enterprise Edition (Formerly Relex)"],"published":"2026-08-20","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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-08-26","vendors":["PTC"]},"summary":"Attackers can bypass access controls in PTC Windchill Risk and Reliability Enterprise Edition, potentially gaining unauthorized access to protected resources.","url":"https://insights.sbomify.com/CVE-2026-77644/"}
