Exploitation evidence

Disclosed: evidence found.
CVE published 11 Nov 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 13 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.

What to do

AI-suggested

A fix for the libcurl vulnerability CVE-2026-11856 is available in libcurl version 8.21.0. Until upgrading, mitigation requires correct application usage by creating a new libcurl easy handle for each different HTTP origin or explicitly clearing authentication-related state before reusing a handle. The Red Hat advisory notes no fixes currently available for the AI Base Images 3.4.8 (ROCm 6.4) themselves. No other mitigations are specified.

Description

A security advisory from Red Hat addresses multiple vulnerabilities affecting Red Hat AI Base Images 3.4.8 (ROCm 6.4), including CVE-2026-1965 and others. One detailed vulnerability (CVE-2026-11856) involves libcurl incorrectly reusing Digest authentication headers across different HTTP origins, potentially leading to information disclosure. This flaw affects libcurl versions from 7.10.6 up to 8.20.0 and is fixed in version 8.21.0. The advisory does not list fixes for the AI Base Images themselves and does not specify affected versions for the overall product. No known exploits in the wild have been reported. The advisory emphasizes correct usage of libcurl handles to mitigate the issue until patched versions are adopted.

Impact

The primary impact is information disclosure due to incorrect reuse of Digest authentication headers in libcurl, which could expose authenticated state to unintended HTTP origins. This may allow attackers to gain unauthorized access to sensitive data or session information. The flaw affects the integrity of authentication state but does not leak credentials directly. No known active exploitation has been reported. The overall severity is rated high by Red Hat for the AI Base Images advisory, with the libcurl issue specifically rated moderate.

Base weaknessOWASP Top 10 A07:2025: Authentication Failures (opens in a new tab)
The product does not validate, or incorrectly validates, a certificate.
Architecture and Design · Implementation
Certificates should be carefully managed and checked to assure that data are encrypted with the intended owner's public key.
Implementation
If certificate pinning is being used, ensure that all relevant properties of the certificate are fully validated before the certificate is pinned, including the hostname.

Architecture and Design
Avoid using cookie data for a security-related decision.
Implementation
Perform thorough input validation (i.e.: server side validation) on the cookie data if you're going to use it for a security related decision.
Architecture and Design
Add integrity checks to detect tampering.

CWE-190Integer Overflow or Wraparound (opens in a new tab)
Base weaknessLikelihood of exploit: Medium
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
Requirements
Ensure that all protocols are strictly defined, such that all out-of-bounds behavior can be identified simply, and require strict conformance to the protocol.
