Twitter Reputation Score Manipulation Vulnerability

CVE-2023-29218 · HIGH Severity

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

The Twitter Recommendation Algorithm through ec83d01 allows attackers to cause a denial of service (reduction of reputation score) by arranging for multiple Twitter accounts to coordinate negative signals regarding a target account, such as unfollowing, muting, blocking, and reporting, as exploited in the wild in March and April 2023. 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.
