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: 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: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 18 Sep 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 8 Nov 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

Red Hat has released an important security advisory with updates in the Red Hat build of Quarkus 3.33.3.SP2 release that address this vulnerability along with others. Users should apply the security update provided by Red Hat for Quarkus 3.33.3.SP2. Before applying this update, ensure all previously released errata relevant to the system have been applied. Refer to Red Hat's official guidance for applying these updates. Patch status is confirmed by the vendor advisory indicating an official fix is available.

Description

CVE-2026-93565 is a vulnerability in the Netty RtspDecoder component used in Red Hat Build of Apache Camel 3.33.3.SP2. It allows remote attackers to bypass method-based access controls by exploiting improper handling of trailing control bytes in RTSP method tokens, enabling method-token smuggling. This flaw can cause malicious RTSP requests to appear legitimate when proxied through Netty-based RTSP proxies. Red Hat has issued an important security advisory addressing this and other vulnerabilities in the Quarkus 3.33.3.SP2 release.

Impact

The vulnerability allows remote attackers to bypass method-based access controls by exploiting the improper handling of trailing control bytes in RTSP method tokens. This can lead to method-token smuggling, causing malicious RTSP requests to be treated as legitimate by Netty-based RTSP proxies. The integrity of the system can be compromised, but there is no direct confidentiality or availability impact reported.
