• Exploited in the wild: not listed in CISA KEV
• EPSS: 1.1% probability of exploitation in the next 30 days
• Public exploit or detection template: none known

Description

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.
