CVE-2023-5318Public exploitNetwork attack vector

Twitter API credential disclosure via hard-coded fallbacks

Published Sep 30, 2023 · Updated Sep 23, 2024

Hard-coded credentials in Microweber before 2.0 allow remote attackers to obtain four bundled Twitter OAuth credentials. The twitter_feed_perform_api_request function assigns embedded access-token, token-secret, consumer-key, and consumer-secret values whenever callers omit them. The published source exposes these values without product authentication, with the reported consequence limited to confidentiality of the associated Twitter account.
