An improper error handling in HTTPS requests management in WP-CLI allows remote attackers able to intercept the communication to remotely disable the certificate verification on WP-CLI side, gaining full control over the communication content, including the ability to impersonate update servers and push malicious updates towards WordPress instances controlled by the vulnerable WP-CLI agent, or push malicious updates toward WP-CLI itself. The vulnerability stems from the fact that the default behavior of `WP_CLI\\Utils\\http_request()` when encountering a TLS handshake error is to disable certificate validation and retry the same request.", "references": [ { "reference_url": "https://api.first.org/data/v1/epss?cve=CVE-2021-29504", "reference_id": "", "reference_type": "", "scores": [ { "value": "0.01149", "scoring_system":
