CVE-2025-27316 pertains to a Cross-Site Request Forgery (CSRF) vulnerability in the hosting.io JPG, PNG Compression and Optimization WordPress plugin. This vulnerability allows attackers to perform unauthorized actions on behalf of legitimate users when they are tricked into interacting with a maliciously crafted request. The issue affects versions from n/a through 1.7.35.
This vulnerability has a CVSS score of 4.3, classifying it as medium severity. Organizations utilizing this plugin should understand the implications of this vulnerability, as it could lead to unauthorized actions that may compromise user data integrity.
The urgency for defenders is moderate, as the attack vector is network-based and requires user interaction. Organizations are encouraged to prioritize patching this vulnerability to safeguard their systems.
As of now, there is no confirmed public exploit, and the vulnerability is classified as deferred. However, organizations should remain vigilant and monitor for any potential exploitation attempts.
Vulnerability Details
The vulnerability allows for CSRF attacks, which could enable an attacker to execute unintended actions on behalf of authenticated users. It has been categorized under CWE-352, indicating a flaw in the CSRF protection mechanism.
The CVSS 3.1 vector string is CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N, with a base score of 4.3. This score reflects low attack complexity, no privileges required, and the necessity for user interaction.
Technical Analysis
The root cause of this vulnerability stems from inadequate CSRF protection within the plugin. The attack vector is network-based, meaning an attacker can exploit this vulnerability remotely. The complexity of the attack is considered low, as it only requires the target user to visit a malicious page or click on a deceptive link.
No privileges are required to exploit this vulnerability, as it targets authenticated users who may not be aware of the malicious actions being performed on their behalf. User interaction is necessary, meaning that the victim must perform some action to trigger the exploit.
The impact on confidentiality is negligible, while the integrity impact is categorized as low, potentially altering a user's data without their consent. There is no expected impact on availability.
Risk & Impact Analysis
Risk to organizations includes unauthorized actions being executed in the context of legitimate users, potentially leading to data manipulation or exposure. The blast radius for this vulnerability could affect all users of the plugin across various WordPress installations.
Organizations should assess the potential impact of this vulnerability within their specific deployment context. Given the CVSS score of 4.3 and the lack of known exploitation, the urgency is moderate, and it should be addressed in the next patch cycle.
