CVE-2025-32913: Libsoup: null pointer dereference in soup_message_headers_get_content_disposition when "filename" parameter is present, but has no value in content-dispositio

Noroxi assessment

Priority: Monitor (action score 30/100)

  • 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: 0.84% (FIRST EPSS); higher than 57.8% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: gitlab.gnome.org/GNOME/libsoup/ libsoup 3.6.2; azl3 libsoup 3.4.4-3 on Azure Linux 3.0 3.4.4-3; azl3 libsoup 3.4.4-6 on Azure Linux 3.0 3.4.4-3.

Low priority for now. Upgrade to gitlab.gnome.org/GNOME/libsoup/ libsoup 3.6.2; azl3 libsoup 3.4.4-3 on Azure Linux 3.0 3.4.4-3; azl3 libsoup 3.4.4-6 on Azure Linux 3.0 3.4.4-3 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

A flaw was found in libsoup, where the soup_message_headers_get_content_disposition() function is vulnerable to a NULL pointer dereference. This flaw allows a malicious HTTP peer to crash a libsoup client or server that uses this function.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.
