Prior to 4.33.0, the unauthenticated Rich Text CSV conversion route writes a multipart upload to the system temporary directory before checking its extension and does not remove the staged file when that validation rejects it. Repeated large rejected uploads, using the normal public CSRF cookie, can persistently consume temporary-disk capacity and may disrupt ApostropheCMS and other services that depend on the same partition. This issue is fixed in version 4.33.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-400","CWE-459","CWE-770"],"references":["https://github.com/apostrophecms/apostrophe/commit/9500b8b0e1d630d5e07fbb5fd2c25ed0943845ce","https://github.com/apostrophecms/apostrophe/commit/f84fd41cbf6c22eb8d0008fc9c25df1f7130b350","https://github.com/apostrophecms/apostrophe/releases/tag/apostrophe@4.33.0","https://github.com/apostrophecms/apostrophe/security/advisories/GHSA-qhcq-9pm2-c9w9","https://github.com/apostrophecms/apostrophe/security/advisories/GHSA-qhcq-9pm2-c9w9"],"products":[],"source":"nvd","synced_at":"2026-10-23T16:39:26.291718493+00:00"},"epss":{"cve":"CVE-2026-113658","score":0.00615,"percentile":0.4915,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-qhcq-9pm2-c9w9","url":"https://osv.dev/vulnerability/GHSA-qhcq-9pm2-c9w9","summary":"ApostropheCMS: Unauthenticated CSV import requests leave rejected uploads in the system temporary directory","modified":"2026-10-20T18:15:04.533207440Z","packages":[{"ecosystem":"npm","name":"apostrophe","purl":"pkg:npm/apostrophe","ranges":["<4.33.0"],"fixed":["4.33.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
