This is due to the use of MAC-free AES-CTR encryption for cart-recovery link tokens — where the 8-byte CTR nonce is carried inside the ciphertext blob and the encryption key is looked up using the attacker-supplied `user_email` GET parameter — combined with an HMAC nonce check in `wcap_email_track_links()` that is only enforced when the `wcap_nonce` parameter is non-empty, allowing complete bypass by omission, and an insecure direct object reference on the decrypted `abandoned_id` with no ownership verification confirming the cart belongs to the email used for decryption. This makes it possible for unauthenticated attackers who possess a single legitimate cart-recovery link (obtained from their own reminder email) to recover the keystream, forge a ciphertext that decrypts to any victim's cart ID, and trigger a call to `wp_set_auth_cookie()` for the victim user — achieving full account takeover of any user who has ever abandoned a cart, including administrators. The auto-login feature defaults to enabled and is forced on during plugin upgrades, meaning all affected installations are exploitable without any additional configuration.","state":0,"publishedAt":"2026-10-14T02:27:38.566+00:00","modifiedAt":"2026-10-14T18:23:49.214+00:00","affected":[{"ecosystem":"Vendor product","name":"Abandoned Cart Pro for WooCommerce","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Tyche Softwares\",\n                    \"product\": \"Abandoned Cart Pro for WooCommerce\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"10.8.0\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8,"severity":"CRITICAL"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/b25b4aed-94b2-4c16-8e4e-39aec4e5e22a?source=cve","https://www.tychesoftwares.com/docs/docs/abandoned-cart-pro-for-woocommerce-new/changelog-abandoned-cart-pro/","https://www.tychesoftwares.com/products/woocommerce-abandoned-cart-pro-plugin/"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-97657","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-97657","identifiers":["CVE-2026-97657"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
