Exploitation evidence

Disclosed: evidence found.
CVE published 13 Nov 2025
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

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 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 official security update for PostgreSQL 16 (version 16.11-1.el10_1) that addresses these vulnerabilities. Users should apply the update promptly following Red Hat's guidance at https://access.redhat.com/articles/11258. No additional mitigation steps are indicated beyond applying the official patch.

Description

This update for postgresql13 fixes the following issues: Security fixes: - CVE-2025-12817: Fixed missing check for CREATE privileges on the schema in CREATE STATISTICS allowed table owners to create statistics in any schema, potentially leading to unexpected naming conflicts (bsc#1253332) - CVE-2025-12818: Fixed several places in libpq were not sufficiently careful about computing the required size of a memory allocation. Sufficiently large inputs could cause integer overflow, resulting in an undersized buffer, which would then lead to writing past the end of the buffer (bsc#1253333) Other fixes: - Update to 13.23 * https://www.postgresql.org/about/news/p-3171/ * https://www.postgresql.org/docs/release/13.23

Impact

The vulnerabilities could allow unauthorized users to perform actions without proper schema CREATE privileges (CVE-2025-12817) and cause memory allocation errors due to integer wraparound in libpq (CVE-2025-12818). These issues may lead to privilege escalation or memory corruption, impacting the security and stability of PostgreSQL installations on affected Red Hat Enterprise Linux 10 systems.

Summary

This advisory addresses two vulnerabilities in PostgreSQL 16 on Red Hat Enterprise Linux 10. CVE-2025-12817 is a privilege check bypass where the CREATE STATISTICS command does not verify schema CREATE privileges, potentially allowing unauthorized actions. CVE-2025-12818 involves an integer wraparound in libpq causing undersized memory allocations, which could lead to memory corruption or related issues. Red Hat has released updated packages (version 16.11-1.el10_1) that fix these vulnerabilities. The advisory rates the security impact as moderate and provides updated RPM packages for various architectures and extended support versions.

CWE-862Missing Authorization (opens in a new tab)
Class weaknessLikelihood of exploit: HighCWE Top 25 (2025): #4OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
Architecture and Design
Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) to enforce the roles at the appropriate boundaries.
Architecture and Design
Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.

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.
Requirements · Language Selection
Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
