The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to a boundary error within the skip_insignificant_whitespace() function when reading server HTTP response. A remote attacker can trick the victim into visiting a specially crafted website and read 1 byte out of bounds.


2) Integer underflow (CVE-ID: CVE-2025-4948)

CWE-ID: CWE-191 - Integer underflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to integer underflow within the soup_multipart_new_from_message() function when handling multipart messages. A remote attacker can trick the victim into visiting a specially crafted website, trigger an integer underflow and crash the application.


3) Resource exhaustion (CVE-ID: CVE-2025-32049)
