Exploitation evidence

Disclosed: evidence found.
CVE published 19 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 26 Oct 2026.

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 or the CVSS exploit maturity 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 the Red Hat redhat/webkit2gtk3 package to 9.8.

AI-suggested

Red Hat has released an important security update that addresses these vulnerabilities. Users of Red Hat Enterprise Linux 9 and its variants should apply the provided update promptly. For detailed update instructions, refer to the Red Hat advisory at https://access.redhat.com/articles/11258. No additional mitigation steps are indicated beyond applying the official patch.

Description

Two security vulnerabilities were found in webkit2gtk3, the GTK port of the WebKit rendering engine. The first (CVE-2025-31205) allows malicious websites to exfiltrate data across origins. The second (CVE-2025-31257) can cause an unexpected crash in Safari when processing crafted web content. Red Hat has released an important security update for Red Hat Enterprise Linux 9 and its variants to address these issues. Users should apply the update to mitigate these vulnerabilities.

Impact

Exploitation of CVE-2025-31205 could lead to unauthorized data leakage across origins, compromising user privacy and security. CVE-2025-31257 may result in denial of service via unexpected crashes in Safari when processing malicious content. Both vulnerabilities pose significant risks to affected systems running webkit2gtk3, particularly in environments using Red Hat Enterprise Linux 9.

Summary

The vulnerabilities in webkit2gtk3 include CVE-2025-31205, which permits cross-origin data exfiltration by malicious websites, and CVE-2025-31257, which may cause Safari to crash unexpectedly when handling maliciously crafted web content. These issues affect the WebKitGTK port on the GTK platform. Red Hat has issued an important security update for Red Hat Enterprise Linux 9 and related variants to fix these vulnerabilities. The update addresses both data leakage and stability issues caused by malicious web content.

Class weaknessLikelihood of exploit: HighCWE Top 25 (2025): #20OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
Architecture and Design · Separation of Privilege
Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.

CWE-416Use After Free (opens in a new tab)
Variant weaknessLikelihood of exploit: HighCWE Top 25 (2025): #7
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
Architecture and Design · Language Selection
Choose a language that provides automatic memory management.
Implementation · Attack Surface Reduction
When freeing pointers, be sure to set them to NULL once they are freed. However, the utilization of multiple or complex data structures may lower the usefulness of this strategy.
