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-2026-4031 in the wild and no public exploit code.\n\nAffected product: wpengine Database Backup for WordPress. 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-2026-4031/ (Markdown: https://insights.sbomify.com/CVE-2026-4031/index.md)","id":"CVE-2026-4031","markdown":"https://insights.sbomify.com/CVE-2026-4031/index.md","name":"CVE-2026-4031","record":{"aliases":["GHSA-7w7g-7m62-6985"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can intercept database backups containing sensitive data if scheduled backups are enabled and the temporary directory is manipulated.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Wordfence","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"The Database Backup for WordPress plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.5.2. This is due to the plugin not restricting access to the wp_db_temp_dir parameter, which controls where database backups are written. This makes it possible for unauthenticated attackers to send a request to wp-cron.php with a poisoned wp_db_temp_dir value pointing to a publicly accessible directory (e.g., wp-content/uploads/), and if a scheduled backup is due, intercept the backup file before it is cleaned up. The backup file has a predictable name based on the database name, table prefix, date, and Swatch Internet Time, making interception reliable. Successful exploitation leads to Sensitive Information Exposure including database credentials, user password hashes, and personally identifiable information. This vulnerability requires that the site administrator has configured scheduled backups.","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":"Database Backup for WordPress \u003c= 2.5.2 - Missing Authorization to Unauthenticated Database Backup Interception","id":"CVE-2026-4031","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":7,"next":{"headline":"CodeColorer \u003c= 0.10.1 - Unauthenticated Stored Cross-Site Scripting via 'class' attribute in 'cc' Comment Shortcode","id":"CVE-2026-4032"},"packages":[],"prev":{"headline":"Database Backup for WordPress \u003c= 2.5.2 - Missing Authorization to Unauthenticated Arbitrary File Read and Deletion","id":"CVE-2026-4030"},"products":["Database Backup for WordPress"],"published":"2026-05-14","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":"partial"},"state":"PUBLISHED","updated":"2026-05-14","vendors":["wpengine"]},"summary":"Unauthenticated attackers can intercept database backups containing sensitive data if scheduled backups are enabled and the temporary directory is manipulated.","url":"https://insights.sbomify.com/CVE-2026-4031/"}
