CVE-2026-101268

Status: DeferredLow (1.7)—

If an attacker is able to convince a victim on a specially crafted link, the victim is logged in to the attacker's customer account. If the victim does not notice this, this might lead to their order details being stored into the attacker's account. The attack only works when the event is available on a different domain than the organizer page.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

🎯 ATT&CK techniques

How this vulnerability is exploited and what the attacker gains, in MITRE ATT&CK terms.

Inferred by deterministic rules from the CVSS vector and CWE. Indicative only.
