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-2026-12949 in the wild and no public exploit code.\n\nAffected product: Wishlist Member. 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-2026-12949/ (Markdown: https://insights.sbomify.com/CVE-2026-12949/index.md)","id":"CVE-2026-12949","markdown":"https://insights.sbomify.com/CVE-2026-12949/index.md","name":"CVE-2026-12949","record":{"aliases":["GHSA-xqxv-q9jf-7cwc"],"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 take over any WordPress account, including administrators, by manipulating registration parameters in the Wishlist Member plugin.","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-640","name":"Weak Password Recovery Mechanism for Forgotten Password"}],"description":"The Wishlist Member plugin for WordPress is vulnerable to Account Takeover via Insufficient Verification of Data Authenticity in versions up to and including 3.34.1. This is due to the wpm_register() function validating the registration cookie only against the GET reg parameter while accepting the POST mergewith and POST wpm_id parameters without verifying that the mergewith user ID references a temporary or incomplete registrant that is bound to the current registration transaction. This makes it possible for unauthenticated attackers to take over any existing WordPress account — including administrator accounts — by supplying an arbitrary user's numeric ID as the mergewith value, which causes wp_update_user() to overwrite the target account's username (additionally written via a direct $wpdb UPDATE), password, email address, first name, and last name with attacker-controlled values, while WordPress password and email change notification emails are explicitly suppressed. When wpm_id references a non-existent membership level, no role key is added to the update payload, causing wp_update_user() to preserve the target user's existing role — including administrator — making full privilege escalation a direct consequence of the takeover.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Wishlist Member X \u003c= 3.34.1 - Unauthenticated Account Takeover via 'mergewith' Parameter","id":"CVE-2026-12949","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"MultiVendorX \u003c= 5.0.18 - Authenticated (Store Manager+) SQL Injection via 'order_by' Parameter","id":"CVE-2026-12951"},"packages":[],"prev":{"headline":"Stored Cross-Site Scripting (XSS)","id":"CVE-2026-12948"},"products":["Wishlist Member"],"published":"2026-08-14","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)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-08-14","vendors":["Wishlist Member"]},"summary":"Unauthenticated attackers can take over any WordPress account, including administrators, by manipulating registration parameters in the Wishlist Member plugin.","url":"https://insights.sbomify.com/CVE-2026-12949/"}
