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-2026-7638 in the wild and no public exploit code.\n\nAffected product: appcheap App Builder – Create Native Android \u0026 iOS Apps On The Flight. 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-2026-7638/ (Markdown: https://insights.sbomify.com/CVE-2026-7638/index.md)","id":"CVE-2026-7638","markdown":"https://insights.sbomify.com/CVE-2026-7638/index.md","name":"CVE-2026-7638","record":{"aliases":["GHSA-5rjg-2j76-x2r5"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Authenticated attackers can modify any user's avatar by manipulating the user_id parameter due to missing authorization checks in the App Builder plugin.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Wordfence","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"The App Builder – Create Native Android \u0026 iOS Apps On The Flight plugin for WordPress is vulnerable to Insecure Direct Object Reference  in all versions up to and including 5.6.0.
