Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-38526 exists.\n\nAffected product: n/a. 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-2026-38526/ (Markdown: https://insights.sbomify.com/CVE-2026-38526/index.md)","id":"CVE-2026-38526","markdown":"https://insights.sbomify.com/CVE-2026-38526/index.md","name":"CVE-2026-38526","record":{"aliases":["GHSA-j8gj-mw5g-642g"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Krayin CRM","requires_auth":"low_privilege","summary":"Authenticated attackers can upload malicious PHP files to the admin endpoint, leading to arbitrary code execution on the server.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":9.9,"severity":"critical","source":"cna","vector":"CVSS:3.1/AC:L/AV:N/A:H/C:H/I:H/PR:L/S:C/UI:N","version":"3.1"},"cwes":[{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"An authenticated arbitrary file upload vulnerability in the /admin/tinymce/upload endpoint of Webkul Krayin CRM v2.2.x allows attackers to execute arbitrary code via uploading a crafted PHP file.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2026-05-16","github_poc":15,"max_poc_stars":7,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-05-16T18:51:51Z","kind":"github_poc","ref":"https://github.com/NathanHimself/CVE-2026-38526-PoC","stars":7,"title":"CVE-2026-38526 | Krayin CRM v2.2.x Authenticated RCE - Unrestricted PHP File Upload via TinyMCE"},{"date":"2026-07-13T21:33:12Z","kind":"github_poc","ref":"https://github.com/CerberusMrXi/KrayinCRM-RCE-Exploit-CVE-2026-38526","stars":3,"title":"CVE-2026-38526 exploit for Krayin CRM v2.2.x - Authenticated RCE via TinyMCE file upload bypass.
