Exploitation evidence

Disclosed: evidence found.
CVE published 25 Mar 2025
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 30 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

Red Hat has released an update for Ansible Automation Platform 2.5 containers that addresses these vulnerabilities. Users should apply the update to their affected Ansible Automation Platform 2.5 installations to remediate these issues. The update includes patched versions of the ansible.controller and ansible.platform collections. No additional mitigation steps are indicated by the vendor advisory.

Description

Red Hat Ansible Automation Platform 2.5 Container Release Update addresses two security vulnerabilities: a Jinja sandbox breakout via the attr filter selecting the format method (CVE-2025-27516) and a potential denial-of-service vulnerability in django.utils.text.wrap() (CVE-2025-26699). These issues affect the ansible-lightspeed-container component. The update also includes fixes for non-security issues and updates to ansible.controller and ansible.platform collections.

Impact

The Jinja sandbox breakout vulnerability (CVE-2025-27516) could allow an attacker to escape the Jinja sandbox environment, potentially leading to unauthorized code execution or information disclosure within the automation platform. The denial-of-service vulnerability (CVE-2025-26699) in django.utils.text.wrap() could allow an attacker to cause service disruption by triggering resource exhaustion. Both vulnerabilities affect the ansible-lightspeed-container component of the platform. No known exploits in the wild have been reported.

CWE-400Uncontrolled Resource Consumption (opens in a new tab)
Class weaknessLikelihood of exploit: High
The product does not properly control the allocation and maintenance of a limited resource.
MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
Architecture and Design
Design throttling mechanisms into the system architecture. The best protection is to limit the amount of resources that an unauthorized user can cause to be expended. A strong authentication and access control model will help prevent such attacks from occurring in the first place.
Architecture and Design
Mitigation of resource exhaustion attacks requires that the target system either: recognizes the attack and denies that user further access for a given amount of time, or; uniformly throttles all requests in order to make it more difficult to consume resources more quickly than they can again be freed.
Architecture and Design
Ensure that protocols have specific limits of scale placed on them.

CWE-1336Improper Neutralization of Special Elements Used in a Template Engine (opens in a new tab)
Base weakness
The product uses a template engine to insert or process externally-influenced input, but it does not neutralize or incorrectly neutralizes special elements or syntax that can be interpreted as template expressions or other code directives when processed by the engine.
Architecture and Design
Choose a template engine that offers a sandbox or restricted mode, or at least limits the power of any available expressions, function calls, or commands.
Implementation
Use the template engine's sandbox or restricted mode, if available.
