An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-89160 exists.\n\nAffected product: PCRE2. 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-2026-89160/ (Markdown: https://insights.sbomify.com/CVE-2026-89160/index.md)","id":"CVE-2026-89160","markdown":"https://insights.sbomify.com/CVE-2026-89160/index.md","name":"CVE-2026-89160","record":{"aliases":["ALPINE-CVE-2026-89160","AZL-100056","AZL-101745","AZL-101763","AZL-101787","AZL-101799","AZL-101817","BELL-CVE-2026-89160","CLSA-2026-1789748039","CLSA-2026-1791400870","DEBIAN-CVE-2026-89160","ECHO-0163-beea-7a1d","GHSA-9qww-pwc4-77qq","GHSA-cv45-8fc2-7w58","MINI-pgw7-83wv-8mxv","UBUNTU-CVE-2026-89160"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"PCRE2 regex library","requires_auth":"none","summary":"An out-of-bounds read in PCRE2 during invalid UTF matching can cause crashes or leak memory, affecting applications using the library.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"pcre2","vendor":"pcre"}],"cvss":{"score":3.7,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"PCRE2 before 10.48 has a pcre2_match out-of-bounds read during the PCRE2_MATCH_INVALID_UTF matching of an invalid UTF subject.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Memory corruption in PCRE2","id":"CVE-2026-89160","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Use after free in PCRE2","id":"CVE-2026-89161"},"packages":[],"prev":{"headline":"Integer overflow in PCRE2","id":"CVE-2026-89158"},"products":["PCRE2"],"published":"2026-09-11","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-8786","kev_date_added":null,"published":"2017-05-05"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-8399","kev_date_added":null,"published":"2017-05-01"},{"cvss_score":7.5,"headline":"Integer overflow in n/a","id":"CVE-2022-41409","kev_date_added":null,"published":"2023-07-18"},{"cvss_score":7.4,"headline":"Use after free in PCRE2","id":"CVE-2026-89161","kev_date_added":null,"published":"2026-09-11"},{"cvss_score":6.9,"headline":"PCRE2: heap-buffer-overflow read in match_ref due to missing boundary restoration in SCS","id":"CVE-2025-58050","kev_date_added":null,"published":"2025-08-27"},{"cvss_score":6.5,"headline":"Integer overflow in PCRE2","id":"CVE-2026-89158","kev_date_added":null,"published":"2026-09-11"},{"cvss_score":5.7,"headline":"Memory corruption in PCRE2","id":"CVE-2026-89157","kev_date_added":null,"published":"2026-09-11"}],"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":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-15","vendors":["PCRE"]},"summary":"An out-of-bounds read in PCRE2 during invalid UTF matching can cause crashes or leak memory, affecting applications using the library.","url":"https://insights.sbomify.com/CVE-2026-89160/"}
