An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-54243 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- statamic/cms (Packagist): affected all versions; fixed in 5.73.24\n- statamic/cms (Packagist): affected all versions; fixed in 5.73.24\n- statamic/cms (Packagist): affected from 6.0.0; fixed in 6.20.1\n- statamic/cms (Packagist): affected from 6.0.0; fixed in 6.20.1\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-2026-54243/ (Markdown: https://insights.sbomify.com/CVE-2026-54243/index.md)","id":"CVE-2026-54243","markdown":"https://insights.sbomify.com/CVE-2026-54243/index.md","name":"CVE-2026-54243","record":{"aliases":["GHSA-h77m-qrj7-jxcw"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Statamic CMS","requires_auth":"none","summary":"Attackers can inject malicious formulas into CSV exports via form submissions, potentially executing code when editors open the file.","user_interaction":"required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":6.1,"severity":"medium","source":"cna","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-1236","name":"Improper Neutralization of Formula Elements in a CSV File"}],"description":"Statamic is a Laravel and Git powered content management system (CMS). Prior to 5.73.24 and 6.20.1, form submission values in src/Forms/Exporters/CsvExporter.php were not neutralized for spreadsheet formula characters when exported to CSV. A submission containing a value beginning with a formula trigger character, such as =, +, -, or @, could be interpreted as a live formula when a Control Panel user opens the export in a spreadsheet application. Form submissions can come from unauthenticated front-end visitors, so the malicious value can be supplied by an anonymous user and is later triggered by an editor opening the export.
