CVE-2024-39926: An issue was discovered in Vaultwarden (formerly Bitwarden_RS) 1.30.3.

MediumCVSS 5.4 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 21/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.45% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: vaultwarden (Alpine:v3.20) 1.32.0; vaultwarden (Alpine:v3.21) 1.32.0-r0.

Low priority for now. Upgrade to vaultwarden (Alpine:v3.20) 1.32.0; vaultwarden (Alpine:v3.21) 1.32.0-r0 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

An issue was discovered in Vaultwarden (formerly Bitwarden_RS) 1.30.3. A stored cross-site scripting (XSS) or, due to the default CSP, HTML injection vulnerability has been discovered in the admin dashboard. This potentially allows an authenticated attacker to inject malicious code into the dashboard, which is then executed or rendered in the context of an administrator's browser when viewing the injected content. However, it is important to note that the default Content Security Policy (CSP) of the application blocks most exploitation paths, significantly mitigating the potential impact.
