Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 4 Dec 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
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 2026-10-26.

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

To mitigate CVE-2025-56427, European organizations should implement the following specific measures: 1) Restrict network access to the ComposioHQ application, limiting exposure to trusted IP ranges or VPN-only access to reduce attack surface. 2) Employ Web Application Firewalls (WAFs) with custom rules to detect and block directory traversal patterns targeting the _download_file_or_dir function. 3) Conduct thorough input validation and sanitization on all file path parameters to prevent traversal sequences such as '../'. 4) Monitor application logs and network traffic for unusual file access requests or patterns indicative of exploitation attempts. 5) If possible, disable or restrict the vulnerable download functionality until a vendor patch is available. 6) Implement strict file system permissions to limit the files accessible by the application process, minimizing the impact of traversal. 7) Maintain an incident response plan to quickly address any detected exploitation attempts. 8) Engage with the vendor or community to obtain updates or patches as soon as they are released. These targeted actions go beyond generic advice and focus on immediate risk reduction in the absence of official patches.

Description

Directory Traversal vulnerability in ComposioHQ v.0.7.20 allows a remote attacker to obtain sensitive information via the _download_file_or_dir function.

Impact

For European organizations, the primary impact of CVE-2025-56427 is the potential unauthorized disclosure of sensitive and confidential information stored on ComposioHQ servers. This can lead to data breaches involving personal data, intellectual property, or business-critical information, potentially violating GDPR and other data protection regulations. The exposure of sensitive files could result in reputational damage, regulatory fines, and loss of customer trust. Since the vulnerability does not affect integrity or availability, operational disruptions are less likely, but the confidentiality breach alone is significant. Organizations in sectors such as finance, healthcare, government, and critical infrastructure that use ComposioHQ are at heightened risk. The lack of authentication requirements and ease of exploitation increase the likelihood of attacks, especially if threat actors develop exploits. The absence of patches means organizations must rely on immediate mitigations to reduce risk. Overall, the vulnerability represents a serious threat to data confidentiality within European enterprises using this software.

MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
Architecture and Design · Separation of Privilege
Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
