An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-1357 exists.\n\nAffected product: wpvividplugins WPvivid — Backup, Migration \u0026 Staging. 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-2026-1357/ (Markdown: https://insights.sbomify.com/CVE-2026-1357/index.md)","id":"CVE-2026-1357","markdown":"https://insights.sbomify.com/CVE-2026-1357/index.md","name":"CVE-2026-1357","record":{"aliases":["GHSA-3cvp-fw5m-7w6r"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can upload arbitrary PHP files to achieve remote code execution due to improper error handling and lack of path sanitization.","user_interaction":"not_required","vuln_class":"file_upload"},"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-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"The Migration, Backup, Staging – WPvivid Backup \u0026 Migration plugin for WordPress is vulnerable to Unauthenticated Arbitrary File Upload in versions up to and including 0.9.123. This is due to improper error handling in the RSA decryption process combined with a lack of path sanitization when writing uploaded files. When the plugin fails to decrypt a session key using openssl_private_decrypt(), it does not terminate execution and instead passes the boolean false value to the phpseclib library's AES cipher initialization. The library treats this false value as a string of null bytes, allowing an attacker to encrypt a malicious payload using a predictable null-byte key. Additionally, the plugin accepts filenames from the decrypted payload without sanitization, enabling directory traversal to escape the protected backup directory. This makes it possible for unauthenticated attackers to upload arbitrary PHP files to publicly accessible directories and achieve Remote Code Execution via the wpvivid_action=send_to_site parameter.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-02-10","github_poc":11,"max_poc_stars":17,"metasploit":0,"nuclei":1,"refs":[{"date":"2026-02-13T09:12:39Z","kind":"github_poc","ref":"https://github.com/halilkirazkaya/CVE-2026-1357","stars":17,"title":"CVE-2026-1357 — WPvivid Backup \u0026 Migration ≤ 0.9.123 Unauthenticated RCE Exploit"},{"date":"2026-02-11T15:26:14Z","kind":"github_poc","ref":"https://github.com/LucasM0ntes/POC-CVE-2026-1357","stars":16,"title":"POC-CVE-2026-1357"},{"date":"2026-02-14T05:15:19Z","kind":"github_poc","ref":"https://github.com/cybertechajju/CVE-2026-1357-POC","stars":9,"title":null},{"date":"2026-02-10T19:38:36Z","kind":"github_poc","ref":"https://github.com/itsismarcos/Exploit-CVE-2026-1357","stars":1,"title":"Exploit CVE-2026-1357"},{"date":"2026-03-10T22:23:22Z","kind":"github_poc","ref":"https://github.com/Nxploited/CVE-2026-1357","stars":1,"title":"Migration, Backup, Staging \u003c= 0.9.123 - Unauthenticated Arbitrary File Upload"},{"date":"2026-08-29T19:38:29Z","kind":"github_poc","ref":"https://github.com/sahmsec/CVE-2026-1357","stars":1,"title":null},{"date":"2026-02-25T07:02:33Z","kind":"github_poc","ref":"https://github.com/rootdirective-sec/CVE-2026-1357-Lab","stars":0,"title":null},{"date":"2026-03-02T06:14:06Z","kind":"github_poc","ref":"https://github.com/CVEs-Labs/CVE-2026-1357","stars":0,"title":null}],"tier":"weaponised"},"has_fix":null,"headline":"Migration, Backup, Staging \u003c= 0.9.123 - Unauthenticated Arbitrary File Upload","id":"CVE-2026-1357","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"file_upload","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"Airleader Master Unrestricted Upload of File with Dangerous Type","id":"CVE-2026-1358"},"packages":[],"prev":{"headline":"Server-side request forgery in Converter for Media – Optimize images | Convert WebP \u0026 AVIF","id":"CVE-2026-1356"},"products":["WPvivid — Backup, Migration \u0026 Staging"],"published":"2026-02-11","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":"2026-04-08","vendors":["wpvividplugins"]},"summary":"Unauthenticated attackers can upload arbitrary PHP files to achieve remote code execution due to improper error handling and lack of path sanitization.","url":"https://insights.sbomify.com/CVE-2026-1357/"}
