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: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
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.

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 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.

AI-suggested

Monitor PDF-XChange Co. Ltd communications and security advisories closely to apply patches immediately once released for version 10.7.3.401.
Until a patch is available, restrict the opening of EMF files or untrusted PDF documents containing embedded EMF content through application whitelisting or file type filtering at email gateways and endpoint security solutions.
Employ sandboxing or isolated environments for opening documents from untrusted sources to contain potential memory disclosure.
Educate users to avoid opening suspicious or unsolicited PDF files, especially those containing embedded graphics or EMF content.
Use endpoint detection and response (EDR) tools to monitor for anomalous application behavior related to PDF-XChange Editor.
Consider deploying application control policies that limit the use of vulnerable PDF-XChange Editor versions or replace it with alternative PDF readers with better security track records.
Implement network-level protections such as email attachment scanning and URL filtering to reduce the risk of malicious document delivery.
Conduct regular audits of software inventory to identify and remediate vulnerable versions promptly.

Description

CVE-2025-58113 is an out-of-bounds read vulnerability in the EMF processing functionality of PDF-XChange Editor version 10.7.3.401. An attacker can exploit this by crafting a malicious EMF file that, when opened by the vulnerable editor, causes the application to read memory outside of its intended bounds. This can lead to the disclosure of sensitive information from the process memory. The vulnerability requires user interaction to open the malicious file but does not require any privileges or authentication. It has a CVSS score of 6.5, indicating a medium severity level. No known exploits are currently reported in the wild.

Impact

For European organizations, the primary impact of CVE-2025-58113 is the potential leakage of sensitive information through memory disclosure. This can compromise confidentiality of internal documents, user credentials, or cryptographic material handled by PDF-XChange Editor. Sectors such as finance, legal, government, and healthcare, which often process sensitive PDF documents, are particularly at risk. The vulnerability could be exploited via phishing campaigns or malicious document distribution, leading to data breaches or espionage. Although the vulnerability does not allow code execution or system compromise, the information disclosure could facilitate further attacks or unauthorized access. The requirement for user interaction means that user awareness and training can mitigate risk, but the widespread use of PDF-XChange Editor in European enterprises increases the attack surface. Additionally, the absence of a patch at the time of disclosure means organizations must rely on interim mitigations, increasing exposure duration. The impact on availability and integrity is negligible, but confidentiality breaches can have severe regulatory and reputational consequences under GDPR and other European data protection laws.
