{"apiVersion":"1.0","identifier":"CVE-2026-75529","description":"Pandora is affected by a stored cross-site scripting vulnerability in the PDF download functionality. The /task-download/<task_id>/.../pdf endpoint verifies that the submitted file is a PDF using Pandora-s content-based file-type detection, but previously returned the file using send_file(task.file.path) without explicitly specifying the MIME type or forcing it to be downloaded as an attachment. Because Flask determines the response MIME type from the filename when a path is supplied, an attacker could submit a file whose content is recognized by Pandora as a PDF while its filename or extension causes the download endpoint to return it with a different, potentially active MIME type. A specially crafted PDF/polyglot file could therefore be served inline and interpreted by a victim-s browser as HTML or another executable web format. If a victim with access to the submitted analysis follows the PDF download link, attacker-controlled script could execute in the security context of the Pandora application, potentially allowing access to application data or actions using the victim-s session. The patch prevents the issue by explicitly returning PDF downloads with Content-Type: application/pdf, forcing Content-Disposition: attachment, and assigning a trusted .pdf filename based on the task UUID.","publishedAt":"2026-08-17T21:16:58","lastModifiedAt":"2026-08-26T16:49:35","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-75529","cvssScore":6.9,"cvssVector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","epssProbability":0.00277,"riskScore":0.71,"affectedProduct":"Pandora","affectedVersions":"unknown","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-75529","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-75529","en":"https://www.redsauce.net/en/cves/CVE-2026-75529","fr":"https://www.redsauce.net/fr/cves/CVE-2026-75529","pt":"https://www.redsauce.net/pt/cves/CVE-2026-75529","de":"https://www.redsauce.net/de/cves/CVE-2026-75529","sk":"https://www.redsauce.net/sk/cves/CVE-2026-75529","el":"https://www.redsauce.net/el/cves/CVE-2026-75529"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-75529"}}
