Exploitation evidence

Disclosed: evidence found.
CVE published 28 May 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-25.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

Upgrade redhat/libsoup to 8.8.5.

AI-suggested

Red Hat has released an important security update for libsoup in Red Hat Enterprise Linux 8.8 Extended Update Support. Users should apply the update as described in the Red Hat advisory RHSA-2025:8252 to remediate these vulnerabilities. For detailed update instructions, refer to https://access.redhat.com/articles/11258. No additional mitigation steps are indicated by the vendor.

Description

The libsoup packages provide an HTTP client and server library for GNOME. Security Fix(es): * libsoup: Heap buffer over-read in `skip_insignificant_space` when sniffing content (CVE-2025-2784) * libsoup: Denial of Service attack to websocket server (CVE-2025-32049) * libsoup: OOB Read on libsoup through function "soup_multipart_new_from_message" in soup-multipart.c leads to crash or exit of process (CVE-2025-32914) * libsoup: Integer Underflow in soup_multipart_new_from_message() Leading to Denial of Service in libsoup (CVE-2025-4948) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Impact

Successful exploitation of these vulnerabilities can lead to denial of service conditions or application crashes in software using libsoup. There is no indication of code execution or data disclosure impacts. The vulnerabilities affect HTTP client and server functionality, including websocket servers and multipart message processing.

Summary

The libsoup library for GNOME contains several security flaws: a heap buffer over-read in the skip_insignificant_space function (CVE-2025-2784), a denial of service vulnerability affecting the websocket server (CVE-2025-32049), an out-of-bounds read in soup_multipart_new_from_message causing crashes (CVE-2025-32914), and an integer underflow in the same function leading to denial of service (CVE-2025-4948). These vulnerabilities can cause crashes or denial of service conditions. Red Hat has issued an update for Red Hat Enterprise Linux 8.8 Extended Update Support to remediate these issues.

CWE-125Out-of-bounds Read (opens in a new tab)
Base weaknessCWE Top 25 (2025): #8
The product reads data past the end, or before the beginning, of the intended buffer.
Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
Architecture and Design · Language Selection
Use a language that provides appropriate memory abstractions.

CWE-191Integer Underflow (Wrap or Wraparound) (opens in a new tab)
Base weakness
The product subtracts one value from another, such that the result is less than the minimum allowable integer value, which produces a value that is not equal to the correct result.
CWE-770Allocation of Resources Without Limits or Throttling (opens in a new tab)
Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #25
The product allocates a reusable resource or group of resources on behalf of an actor without imposing any intended restrictions on the size or number of resources that can be allocated.
Requirements
Clearly specify the minimum and maximum expectations for capabilities, and dictate which behaviors are acceptable when resource allocation reaches limits.
Architecture and Design
Limit the amount of resources that are accessible to unprivileged users. Set per-user limits for resources. Allow the system administrator to define these limits. Be careful to avoid CWE-410.
Architecture and Design
Design throttling mechanisms into the system architecture. The best protection is to limit the amount of resources that an unauthorized user can cause to be expended.
