{"apiVersion":"1.0","identifier":"CVE-2026-54505","description":"TREK is a collaborative travel planner. Prior to 3.1.0, when the Journey add-on is enabled, TREK interpolates the unescaped activeSuggestion.title value into journey.frontpage.suggestionText through client/src/i18n/TranslationContext.tsx and renders the result with dangerouslySetInnerHTML in client/src/pages/JourneyPage.tsx. A trip owner can store HTML in a qualifying trip title, and GET /api/journeys/suggestions returns that title through getSuggestions(userId) to a collaborator who opens the authenticated Journey page. The markup is inserted as live DOM in the collaborator-s session, enabling content spoofing and UI redress, although the default Content Security Policy blocks inline handlers and script execution. This issue is fixed in version 3.1.0.","publishedAt":"2026-08-20T22:17:21","lastModifiedAt":"2026-08-25T16:16:54","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-54505","cvssScore":2,"cvssVector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:A/VC:N/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":0.00426,"riskScore":0.21,"affectedProduct":"TREK","affectedVersions":"<3.1.0","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-54505","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-54505","en":"https://www.redsauce.net/en/cves/CVE-2026-54505","fr":"https://www.redsauce.net/fr/cves/CVE-2026-54505","pt":"https://www.redsauce.net/pt/cves/CVE-2026-54505","de":"https://www.redsauce.net/de/cves/CVE-2026-54505","sk":"https://www.redsauce.net/sk/cves/CVE-2026-54505","el":"https://www.redsauce.net/el/cves/CVE-2026-54505"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-54505"}}
