An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-97657 in the wild and no public exploit code.\n\nAffected product: Tyche Softwares Abandoned Cart Pro for WooCommerce. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-97657/ (Markdown: https://insights.sbomify.com/CVE-2026-97657/index.md)","id":"CVE-2026-97657","markdown":"https://insights.sbomify.com/CVE-2026-97657/index.md","name":"CVE-2026-97657","record":{"aliases":["GHSA-j8r3-gcq3-h8jj"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["account_takeover","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can bypass authentication and take over any user account, including administrators, by exploiting weak encryption and missing ownership checks in cart recovery links.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Wordfence","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"The Abandoned Cart Pro for WooCommerce plugin for WordPress is vulnerable to Authentication Bypass via Malleable Encryption and Bypassable HMAC in all versions up to, and including, 10.8.0. 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.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-10-14","github_poc":1,"max_poc_stars":1,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-10-14T11:07:19Z","kind":"github_poc","ref":"https://github.com/murrez/CVE-2026-97657","stars":1,"title":"CVE-2026-97657 – Authentication Bypass \u0026 Account Takeover | Pocbit"}],"tier":"poc_unverified"},"has_fix":null,"headline":"Auth bypass in Abandoned Cart Pro for WooCommerce","id":"CVE-2026-97657","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Cross-site scripting in WPC Product Options for WooCommerce","id":"CVE-2026-97660"},"packages":[],"prev":{"headline":"Langflow OSS is affected by multiple vulnerabilities","id":"CVE-2026-97655"},"products":["Abandoned Cart Pro for WooCommerce"],"published":"2026-10-14","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-14","vendors":["Tyche Softwares"]},"summary":"Unauthenticated attackers can bypass authentication and take over any user account, including administrators, by exploiting weak encryption and missing ownership checks in cart recovery links.","url":"https://insights.sbomify.com/CVE-2026-97657/"}
