Exploitation evidence

Disclosed: evidence found.
CVE published 1 Oct 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.

What to do

AI-suggested

No mitigation or patch currently meets Red Hat's criteria for deployment, ease of use, applicability, or stability. Users should monitor Red Hat advisories for updates and consider consulting with Red Hat technical account managers if applicable. Red Hat recommends following the Red Hat Satellite documentation for installation and configuration guidance. No immediate action is mandated by Red Hat beyond awareness and monitoring.

Description

A vulnerability (CVE-2026-84292) was found in the fast-uri component used by Red Hat Lightspeed in Satellite. The flaw involves improper serialization of the port component of a URI without validating its content, allowing an attacker to inject authority delimiters. This can cause the intended host to be demoted to user information and redirect network traffic to an attacker-controlled host, potentially compromising communication integrity. No fix is currently available that meets Red Hat's criteria for deployment and stability.

Impact

The vulnerability allows remote attackers to redirect network traffic to arbitrary hosts by injecting authority delimiters into the port component of a URI. This compromises the integrity of communications and can lead to information disclosure as applications may trust the attacker-controlled host. The flaw does not require privileges or user interaction and has a low attack complexity. Confidentiality and availability impacts are not indicated.

CWE-140Improper Neutralization of Delimiters (opens in a new tab)
Base weakness
The product does not neutralize or incorrectly neutralizes delimiters.
Implementation · Input Validation
Developers should anticipate that delimiters will be injected/removed/manipulated in the input vectors of their product. Use an appropriate combination of denylists and allowlists to ensure only valid, expected and appropriate input is processed by the system.
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.
Implementation · Output Encoding
While it is risky to use dynamically-generated query strings, code, or commands that mix control and data together, sometimes it may be unavoidable. Properly quote arguments and escape any special characters within those arguments.

CWE-1289Improper Validation of Unsafe Equivalence in Input (opens in a new tab)
Base weakness
The product receives an input value that is used as a resource identifier or other type of reference, but it does not validate or incorrectly validates that the input is equivalent to a potentially-unsafe value.
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.
