Pretalx
Monthly
Stored cross-site scripting in pretalx conference planning software before 2026.1.0 lets any registered user inject HTML/JavaScript via submission titles, speaker display names, or user names/emails, which executes in an organiser's browser when the organiser's typeahead search matches the malicious record. Because the backend rendered these fields into the search dropdown via innerHTML string interpolation, the injected script runs in the authenticated organiser context and can steal the CSRF token and perform actions on the victim's behalf. No public exploit identified at time of analysis, and EPSS is very low (0.03%), but a scope-changing high-impact CVSS (8.7) and a vendor GHSA make this a credible privilege-escalation vector.
pretalx 2.3.1 before 2.3.2 allows path traversal in HTML export (a non-default feature). Rated medium severity (CVSS 4.3), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available.
Unauthenticated attackers can inject malicious HTML into user-controlled template placeholders in pretalx prior to 2026.1.0, enabling arbitrary HTML-rendered emails to be sent from the conference organizer's legitimate sender address. By registering an account with a crafted display name containing HTML or markdown link syntax and triggering a password reset, an attacker can deliver convincing phishing emails that pass SPF/DKIM/DMARC validation, with user interaction (victim clicking password-reset link) required. This vulnerability is fixed in version 2026.1.0.
pretalx 2.3.1 before 2.3.2 allows path traversal in HTML export (a non-default feature). Rated medium severity (CVSS 6.5), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available.
