NOTE: Vendor states that allowing users to unfollow, mute, block, and report tweets and accounts and the impact of these negative engagements on Twitter’s ranking algorithm is a conscious design decision, rather than a security vulnerability.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":[],"references":["https://github.com/twitter/the-algorithm/issues/1386","https://github.com/twitter/the-algorithm/tree/ec83d01dcaebf369444d75ed04b3625a0a645eb9","https://steventey.com/blog/twitter-algorithm","https://twitter.com/Kaptain_Kobold/status/1642379706925477888","https://twitter.com/aakashg0/status/1641976913165180929"],"products":["twitter:recommendation_algorithm"],"source":"nvd","synced_at":"2026-10-19T21:37:48.383111019+00:00"},"epss":{"cve":"CVE-2023-29218","score":0.01091,"percentile":0.65402,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
