Integrity: None
Availability: None

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Adjacent: The vulnerable component is bound to the network stack, but the attack is limited at the protocol level to a logically adjacent topology. This can mean an attack must be launched from the same shared physical (e.g., Bluetooth or IEEE 802.11) or logical (e.g., local IP subnet) network, or from within a secure or otherwise limited administrative domain (e.g., MPLS, secure VPN to an administrative network zone).
Attack Complexity: High: A successful attack depends on conditions beyond the attacker's control. That is, a successful attack cannot be accomplished at will, but requires the attacker to invest in some measurable amount of effort in preparation or execution against the vulnerable component before a successful attack can be expected. For example, a successful attack may require an attacker to: gather knowledge about the environment in which the vulnerable target/component exists; prepare the target environment to improve exploit reliability; or inject themselves into the logical network path between the target and the resource requested by the victim in order to read and/or modify network communications (e.g., a man in the middle attack).
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 25 Sep 2026
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.

Description

It was discovered that PHP did not properly validate the size of MySQL server packets in the mysqlnd driver. A malicious server could possibly use this issue to cause PHP to crash, resulting in a denial of service. This issue was only addressed in Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, Ubuntu 24.04 LTS, Ubuntu 26.04 LTS, and Ubuntu 26.10. (CVE-2025-1218) It was discovered that PHP incorrectly handled response buffer sizes in the SOAP HTTP client. A malicious server could possibly use this issue to cause PHP to crash, resulting in a denial of service, or execute arbitrary code. (CVE-2025-14181) It was discovered that PHP incorrectly handled certain TAR archive headers in the Phar extension. An attacker could possibly use this issue to inject arbitrary files into a crafted archive. (CVE-2026-6103) It was discovered that PHP did not limit recursion depth when parsing certain SOAP requests. A remote attacker could possibly use this issue to cause PHP to crash, resulting in a denial of service. (CVE-2026-91765) It was discovered that PHP incorrectly handled authentication headers when following HTTP redirects. A remote attacker could possibly use this issue to obtain sensitive information. (CVE-2026-91766) It was discovered that PHP incorrectly handled wildcard names in TLS server certificates. A malicious server could possibly use this issue to cause PHP to crash, resulting in a denial of service. This issue did not affect Ubuntu 14.04 LTS. (CVE-2026-91767) It was discovered that PHP incorrectly validated IPv6 client addresses in the FastCGI client access check. A remote attacker could possibly use this issue to bypass access restrictions. This issue did not affect Ubuntu 14.04 LTS. (CVE-2026-91768) It was discovered that PHP incorrectly performed TLS peer name verification. A remote attacker could possibly use this issue to impersonate a trusted server. (CVE-2026-91769) It was discovered that PHP incorrectly handled certain stream filter options. An attacker could possibly use this issue to obtain sensitive information. (CVE-2026-92842) It was discovered that PHP incorrectly handled empty Location headers when following HTTP redirects. A malicious server could possibly use this issue to redirect the client to an unintended location. This issue did not affect Ubuntu 14.04 LTS. (CVE-2026-93682)
