Exploitation evidence

Disclosed: evidence found.
CVE published 14 Apr 2026
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
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 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 advises running Composer commands only on projects and dependencies from trusted sources. To mitigate the risk, users should use the '--prefer-dist' option or configure 'preferred-install: dist' to avoid installing dependencies from source, which triggers the vulnerable code path.

Description

This update for php-composer2 fixes the following issues: - CVE-2026-45793: Github Actions issued `GITHUB_TOKEN` disclosure in GitHub Actions logs (bsc#1271504). - CVE-2026-59946: path traversal in package `bin` field lets dependencies `chmod` arbitrary host files (bsc#1271151). - CVE-2026-59947: URL-embedded HTTP-Basic username leaks to verbose logs (bsc#1271129). - CVE-2026-59948: arbitrary file write outside `vendor`directory via malicious transitive package name (bsc#1271122). Changes for php-composer2: - fix byte-swapped signature on s390x can cause broken or unsupported signature (bsc#1271729).

Impact

Successful exploitation allows attackers to execute arbitrary operating system commands with the privileges of the Composer process. This can lead to unauthorized code execution, data modification or disclosure, denial of service, and potential system compromise. Because the commands execute as the application user, malicious activities may appear to originate from the legitimate application or owner. The vulnerability affects confidentiality, integrity, and availability of the impacted systems.

Summary

The vulnerability (CVE-2026-40261) in Composer's Perforce::syncCodeBase() function allows an attacker to inject arbitrary shell commands by supplying a malicious source reference with shell metacharacters. This occurs because the parameter is appended to a shell command without proper escaping. The flaw can be exploited when installing or updating dependencies from source, including default behavior for dev-prefixed versions, leading to arbitrary command execution. Red Hat has issued an advisory (RHSA-2026:8165) covering this issue in their Hardened Images RPMs, specifically composer-2.9.7-1.hum1 (noarch). The vulnerability is associated with CWE-78 (OS Command Injection) and CWE-74. No explicit patch link is provided in the advisory, but mitigation guidance is given.

CWE-74Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') (opens in a new tab)
Class weaknessLikelihood of exploit: HighOWASP Top 10 A05:2025: Injection (opens in a new tab)
The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
Requirements
Programming languages and supporting technologies might be chosen which are not subject to these issues.
Implementation
Utilize an appropriate mix of allowlist and denylist parsing to filter control-plane syntax from all input.

Architecture and Design
If at all possible, use library calls rather than external processes to recreate the desired functionality.
Architecture and Design · Operation · Sandbox or Jail
Run the code in a "jail" or similar sandbox environment that enforces strict boundaries between the process and the operating system. This may effectively restrict which files can be accessed in a particular directory or which commands can be executed by the software.
Architecture and Design · Attack Surface Reduction
For any data that will be used to generate a command to be executed, keep as much of that data out of external control as possible. For example, in web applications, this may require storing the data locally in the session's state instead of sending it out to the client in a hidden form field.
