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-2026-0668 in the wild and no public exploit code.\n\nAffected product: Wikimedia Foundation MediaWiki - VisualData Extension. 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-2026-0668/ (Markdown: https://insights.sbomify.com/CVE-2026-0668/index.md)","id":"CVE-2026-0668","markdown":"https://insights.sbomify.com/CVE-2026-0668/index.md","name":"CVE-2026-0668","record":{"aliases":["GHSA-6p52-pvr6-5x2c"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"MediaWiki VisualData extension","requires_auth":"none","summary":"Attackers can cause service disruption in MediaWiki VisualData extension by submitting crafted input that triggers exponential regex processing.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"wikimedia-foundation","cpe":[{"product":"visualdata","vendor":"wikisphere"}],"cvss":{"score":5.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-1333","name":"Inefficient Regular Expression Complexity"}],"description":"Inefficient Regular Expression Complexity vulnerability in Wikimedia Foundation MediaWiki - VisualData Extension allows Regular Expression Exponential Blowup.This issue affects MediaWiki - VisualData Extension: 1.45.","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":"VisualData extension: Regular Expression Denial of Service (ReDoS) via crafted user input","id":"CVE-2026-0668","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"Path Traversal vulnerability in CSS extension on certain web servers","id":"CVE-2026-0669"},"packages":[],"prev":{"headline":"Other in RemoteConnect","id":"CVE-2026-0667"},"products":["MediaWiki - VisualData Extension"],"published":"2026-01-07","related":[],"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":"partial"},"state":"PUBLISHED","updated":"2026-01-07","vendors":["Wikimedia Foundation"]},"summary":"Attackers can cause service disruption in MediaWiki VisualData extension by submitting crafted input that triggers exponential regex processing.","url":"https://insights.sbomify.com/CVE-2026-0668/"}
