CVE-2025-70887 is a high-severity privilege escalation vulnerability affecting ralphje Signify prior to version 0.9.2. This vulnerability allows a remote attacker to escalate privileges through the signed_data.py and context.py components. With a CVSS score of 8.8, this vulnerability poses a serious risk to organizations leveraging the affected software.
The impact of this vulnerability is significant, as attackers may leverage it to gain unauthorized access to sensitive data and systems, compromising confidentiality, integrity, and availability. Organizations using this version of Signify should prioritize addressing this vulnerability to safeguard their assets.
As of now, there are no known exploits publicly available for this vulnerability, and it is not listed in the Known Exploited Vulnerabilities (KEV) catalog. However, the potential for exploitation remains, making it essential for organizations to implement mitigation strategies.
Organizations should prioritize patching immediately to mitigate the risks associated with CVE-2025-70887. Delaying remediation may expose systems to unnecessary risks.
Vulnerability Details
An issue in ralphje Signify before v.0.9.2 allows a remote attacker to escalate privileges via the signed_data.py and context.py components. The vulnerability has a CVSS score of 8.8, indicating a high severity level. Affected configurations include all versions prior to the vendor patch, specifically those identified with the CPE: cpe:2.3:a:ralphje:signify:*:*:*:*:*:python:*:*.
The vulnerability falls under CWE-269, which is associated with privilege escalation. The disclosed date of this vulnerability is March 25, 2026, and it was last modified on April 1, 2026.
Technical Analysis
The root cause of CVE-2025-70887 lies in the improper handling of signed data within the affected components. The attack vector for this vulnerability is through a network, making it accessible to remote attackers. The attack complexity is rated as low, and only low privileges are required to exploit this vulnerability, meaning that even authenticated users could potentially leverage it.
User interaction is not required for exploitation, which increases the risk further. The vulnerability has a high impact on confidentiality, integrity, and availability, as successful exploitation could lead to unauthorized access and manipulation of sensitive data and services.
Risk & Impact Analysis
Risk to organizations includes the potential for unauthorized access to sensitive systems and data, leading to severe operational impacts. Given the high CVSS score of 8.8, organizations should recognize the urgency of addressing this vulnerability. The exploitation of this vulnerability could significantly broaden the blast radius, impacting not only the immediate systems but also extending to interconnected services and data.
Organizations should address this vulnerability in their priority patch cycle to minimize exposure and risk. The lack of known exploits does not mitigate the need for immediate remediation, as vulnerabilities of this severity can be rapidly weaponized once disclosed.
