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: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
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: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.
Exploit Code Maturity: Unproven: No exploit code is available, or an exploit is theoretical.
Remediation Level: Official Fix: A complete vendor solution is available. Either the vendor has issued an official patch, or an upgrade is available.
Report Confidence: Confirmed: Detailed reports exist, or functional reproduction is possible (functional exploits may provide this). Source code is available to independently verify the assertions of the research, or the author or vendor of the affected code has confirmed the presence of the vulnerability.

Exploitation evidence

Disclosed: evidence found.
CVE published 12 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 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 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. Monitor Microsoft’s official channels closely for the release of security patches addressing CVE-2025-53760 and apply them immediately upon availability. 2. Until patches are available, restrict SharePoint server outbound network access using firewall rules or network segmentation to limit the ability of SSRF to reach internal resources. 3. Implement strict access controls and least privilege principles for SharePoint users and service accounts to minimize the risk posed by authorized attackers. 4. Enable detailed logging and monitoring of SharePoint server network activity, focusing on unusual or unexpected outbound HTTP requests that could indicate SSRF exploitation attempts. 5. Conduct internal vulnerability assessments and penetration testing to identify potential SSRF attack vectors within the SharePoint environment. 6. Review and harden SharePoint configurations to disable or restrict features that allow external or internal URL fetching if not required. 7. Educate IT and security teams about SSRF risks and detection techniques specific to SharePoint environments. 8. Consider deploying Web Application Firewalls (WAFs) with SSRF detection capabilities to provide an additional layer of defense.

Description

Server-side request forgery (ssrf) in Microsoft Office SharePoint allows an authorized attacker to elevate privileges over a network.

Impact

For European organizations, the impact of CVE-2025-53760 can be substantial. SharePoint is widely deployed across Europe in both public and private sectors for document management and collaboration, often integrated with sensitive internal systems. Exploitation could allow attackers to bypass network controls and access internal services that are otherwise inaccessible externally, leading to unauthorized data disclosure or further compromise. This is especially critical for organizations handling personal data under GDPR, as data breaches could result in regulatory penalties and reputational damage. The vulnerability's ability to elevate privileges means attackers could gain higher access levels, potentially enabling lateral movement and persistence within networks. Critical infrastructure sectors such as finance, healthcare, government, and energy, which rely heavily on Microsoft products, could face increased risks. The absence of known exploits currently provides a window for proactive defense, but the high CVSS score and ease of exploitation (low complexity, no user interaction) indicate that threat actors may develop exploits rapidly. Therefore, European organizations must treat this vulnerability as a high priority to prevent potential data breaches and operational disruptions.
