An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-15931 exists.\n\nAffected product: Unknown Simple Membership. 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-2026-15931/ (Markdown: https://insights.sbomify.com/CVE-2026-15931/index.md)","id":"CVE-2026-15931","markdown":"https://insights.sbomify.com/CVE-2026-15931/index.md","name":"CVE-2026-15931","record":{"aliases":["GHSA-cc2x-fmqx-2g5v"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["account_takeover","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can inject malicious JavaScript via PayPal subscriber names, leading to admin session hijacking in the Simple Membership plugin.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":6.1,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"The Simple Membership WordPress plugin before 4.7.8 does not sanitise a subscriber name value received from an unauthenticated payment approval request, nor escape it when displaying it in the administration dashboard, allowing unauthenticated attackers to store arbitrary JavaScript that executes in an administrator's session.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"Simple Membership \u003c 4.7.8 - Unauthenticated Stored XSS via PayPal Subscription Subscriber Name","id":"CVE-2026-15931","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Support Genix Lite \u003c 1.4.48 - Unauthenticated Arbitrary File Read via Path Traversal","id":"CVE-2026-15932"},"packages":[],"prev":{"headline":"Simple Membership \u003c 4.7.8 - Unauthenticated Administrator Account Takeover via Registration Username Collision","id":"CVE-2026-15930"},"products":["Simple Membership"],"published":"2026-08-03","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":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-03","vendors":["Unknown"]},"summary":"Unauthenticated attackers can inject malicious JavaScript via PayPal subscriber names, leading to admin session hijacking in the Simple Membership plugin.","url":"https://insights.sbomify.com/CVE-2026-15931/"}
