Attack Vector: Local
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: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
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 11 Nov 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 implement strict controls on file handling by restricting the types of files that can be opened with Adobe Format Plugins, especially from untrusted sources. 2. Educate users to avoid opening files from unknown or suspicious origins and increase awareness of phishing attempts that may deliver malicious files. 3. Disable or uninstall Adobe Format Plugins where feasible until a security patch is released. 4. Monitor and audit file access and plugin usage to detect anomalous behavior indicative of exploitation attempts. 5. Employ application whitelisting and sandboxing to isolate Adobe applications and limit the impact of potential exploitation. 6. Once Adobe releases a patch, prioritize timely deployment across all affected systems. 7. Use endpoint detection and response (EDR) tools to identify suspicious memory access patterns or unusual application behavior. 8. Implement network-level protections such as email filtering and attachment scanning to reduce the likelihood of malicious files reaching end users. These measures go beyond generic advice by focusing on controlling the attack vector (malicious files) and limiting plugin exposure until a patch is available.

Description

Format Plugins versions 1.1.1 and earlier are affected by an Out-of-bounds Read vulnerability that could lead to memory exposure. An attacker could leverage this vulnerability to disclose sensitive information stored in memory. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

Impact

For European organizations, the primary impact of CVE-2025-61840 is the potential exposure of sensitive information through memory disclosure. This can undermine confidentiality, especially in sectors such as finance, healthcare, government, and critical infrastructure where Adobe products are widely used. Attackers could leverage this vulnerability to extract confidential data, which may facilitate further attacks such as credential theft or espionage. Although the vulnerability does not affect system integrity or availability, the leakage of sensitive data can lead to regulatory non-compliance under GDPR and other data protection laws, resulting in legal and financial repercussions. The requirement for user interaction limits mass exploitation but does not eliminate risk, particularly in environments with high file exchange volumes or where users may be targeted with phishing campaigns. The absence of known exploits currently provides a window for proactive mitigation. However, once exploited, the impact on confidentiality can be significant, especially if sensitive memory contents are exposed.

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.
