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

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: High: The attacker is authorized with (i.e., requires) privileges that provide significant (e.g., administrative) control over the vulnerable component that could affect component-wide settings and files.
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: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 30 Jul 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: 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 29 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.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), 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.

AI-suggested

All disclosed vulnerabilities have official patches or fixes available. The deserialization vulnerability in Application Integration was patched on September 11, 2026, and the Compute Engine authorization issue was patched on August 31, 2026; no customer action is required for these. For the PHP vulnerabilities, upgrade to PHP versions 8.2.35, 8.3.36, 8.4.27, or 8.5.12 where applicable; no fixed releases exist for PHP 8.1 or earlier. Regarding the compromised CA certificates, Google Cloud is actively managing revocations and mitigations. Customers managing their own operating systems or container images should update trust stores and apply security updates as recommended by Google. No further immediate action is required for managed Google Cloud services.

Description

Multiple vulnerabilities affecting VMware products and related Google Cloud services have been disclosed. These include a deserialization of untrusted data vulnerability in Application Integration, an incorrect authorization vulnerability in Compute Engine, and critical PHP core vulnerabilities impacting Drupal-based Apigee developer portals. Additionally, private keys associated with several eMudhra subordinate CA certificates have been compromised, leading to certificate revocations affecting various Google Cloud and Firebase products. Google Cloud infrastructure remains uncompromised, and patches or mitigations have been applied or are available for these issues.

Impact

The vulnerabilities could allow authenticated users to execute arbitrary code via deserialization attacks, unauthorized users to exfiltrate disk data without proper permissions, and unauthenticated attackers to remotely execute code on vulnerable PHP servers. The CA key compromise undermines trust in affected certificates, potentially impacting secure communications and authentication for various Google Cloud and Firebase services. However, Google Cloud infrastructure itself remains secure with no evidence of exploitation. The impact on Apigee is limited to Drupal-based developer portals. These issues pose critical and high risks if unpatched.
