• Severity: high (CVSS 8.8 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.5% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2021-01-20 · updated 2026-06-17
• Weakness: CWE-352

Description

This affects the package com.softwaremill.akka-http-session:core_2.12 from 0 and before 0.6.1; all versions of package com.softwaremill.akka-http-session:core_2.11; the package com.softwaremill.akka-http-session:core_2.13 from 0 and before 0.6.1. CSRF protection can be bypassed by forging a request that contains the same value for both the X-XSRF-TOKEN header and the XSRF-TOKEN cookie value, as the check in randomTokenCsrfProtection only checks that the two values are equal and non-empty.

Affected products

• Softwaremill Akka-Http-Session: before 0.6.1 — fixed in 0.6.1

How to fix

Upgrade to a fixed version: Softwaremill Akka-Http-Session 0.6.1. Check the vendor advisory for mitigations.
