{"id":"CVE-2025-70129","details":"If the anti spam-captcha functionality in PluXml versions 5.8.22 and earlier is enabled, a captcha challenge is generated with a format that can be automatically recognized for articles, such that an automated script is able to solve this anti-spam mechanism trivially and publish spam comments. The details of captcha challenge are exposed within document body of articles with comments & anti spam-captcha functionalities enabled, including \"capcha-letter\", \"capcha-word\" and \"capcha-token\" which can be used to construct a valid post request to publish a comment. As such, attackers can flood articles with automated spam comments, especially if there are no other web defenses available.","modified":"2026-07-08T08:12:20.665734593Z","published":"2026-03-10T00:00:00Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/70xxx/CVE-2025-70129.json","cna_assigner":"mitre"},"references":[{"type":"WEB","url":"https://github.com/forest4x/vuln-research-public/blob/main/CVE-2025-70129.pdf"},{"type":"WEB","url":"https://youtu.be/dD2olE4yMqY"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/70xxx/CVE-2025-70129.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-70129"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/pluxml/pluxml","events":[{"introduced":"0"},{"last_affected":"1da14ae8d9b6937173e5917682ae75664d784911"}],"database_specific":{"cpe":"cpe:2.3:a:pluxml:pluxml:*:*:*:*:*:*:*:*","source":"CPE_RANGE","extracted_events":[{"introduced":"0"},{"last_affected":"5.8.22"}]}}],"versions":["v5.8.22-urlredirection","v5.8.22","v5.8.21","v5.8.20","v5.8.9","5.8.9","v5.8.19","v5.8.18","v5.8.17","v5.8.16","v5.8.15","v5.8.14","v5.8.13","v5.8.12","v5.8.8","v5.8.7","v5.8.5","v5.8.3","v5.8.2","v5.8.1","v5.8","v5.7","5.6","5.5","5.4"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-70129.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N"}]}
