Attack Vector: Network
Attack Complexity: Low
Privileges Required: None
User Interaction: Required
Scope: Unchanged
Confidentiality: High
Integrity: None
Availability: None

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.

Exploitation evidence

Disclosed: evidence found.
CVE published 5 Aug 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

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 2026-10-25.

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

1. Immediately restrict or monitor the use of PDF-XChange Editor version 10.6.0.396, especially for opening documents from untrusted or external sources. 2. Educate users to avoid opening unexpected or suspicious PDF files, particularly those containing embedded EMF content. 3. Employ advanced endpoint detection and response (EDR) tools capable of detecting anomalous memory access patterns or suspicious file behaviors related to EMF processing. 4. Use network-level controls to block or quarantine emails and downloads containing PDFs with embedded EMF files from untrusted origins. 5. Implement application whitelisting and sandboxing to limit the impact of potential exploitation. 6. Monitor vendor communications closely and apply patches or updates as soon as they become available. 7. Consider deploying PDF viewers with robust sandboxing or alternative software that does not process EMF files in the same manner. 8. Conduct regular security awareness training focusing on phishing and social engineering tactics that could deliver malicious PDFs. 9. Review and enhance data loss prevention (DLP) policies to detect unusual data access or exfiltration attempts that might follow exploitation.

Description

An out-of-bounds read vulnerability exists in the EMF functionality of PDF-XChange Co. Ltd PDF-XChange Editor 10.6.0.396. By using a specially crafted EMF file, an attacker could exploit this vulnerability to perform an out-of-bounds read, potentially leading to the disclosure of sensitive information.

Impact

For European organizations, the primary impact of CVE-2025-47152 is the potential unauthorized disclosure of sensitive information through memory exposure when opening malicious EMF files embedded in PDFs. This can compromise confidentiality of internal documents, intellectual property, or personal data, potentially violating GDPR requirements. Sectors with high document handling volumes—such as legal firms, financial institutions, healthcare providers, and government agencies—are particularly at risk. While the vulnerability does not affect system integrity or availability, the leakage of sensitive data could lead to reputational damage, regulatory fines, and targeted follow-on attacks. Since exploitation requires user interaction, phishing or social engineering campaigns could be used to deliver malicious PDFs. The absence of a patch increases exposure duration, emphasizing the need for proactive defenses. Organizations relying on PDF-XChange Editor version 10.6.0.396 should consider this vulnerability a significant risk to data confidentiality.

Base weaknessCWE Top 25 (2025): #8
The product reads data past the end, or before the beginning, of the intended buffer.
Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
Architecture and Design · Language Selection
Use a language that provides appropriate memory abstractions.
