CVE-2025-32789 WRITEUP LOW WRITEUP
EspoCRM < 9.0.7 - Exposure of Sensitive Information via User Password Hash Sorting
EspoCRM is an Open Source Customer Relationship Management software. Prior to version 9.0.7, users can be sorted by their password hash. This flaw allows an attacker to make assumptions about the hash values of other users stored in the password column of the user table, based on the results of the sorted list of users. Although unlikely, if an attacker knows the hash value of their password, they can change the password and repeat the sorting until the other user's password hash is fully revealed. This issue is patched in version 9.0.7.
CVSS 3.1
CVE-2023-46736 WRITEUP MEDIUM WRITEUP
EspoCRM <8.0.5 - Server-Side Request Forgery via Image URL Upload
EspoCRM is an Open Source CRM (Customer Relationship Management) software. In affected versions there is Server-Side Request Forgery (SSRF) vulnerability via the upload image from url api. Users who have access to `the /Attachment/fromImageUrl` endpoint can specify URL to point to an internal host. Even though there is check for content type, it can be bypassed by redirects in some cases. This SSRF can be leveraged to disclose internal information (in some cases), target internal hosts and bypass firewalls. This vulnerability has been addressed in commit `c536cee63` which is included in release version 8.0.5. Users are advised to upgrade. There are no known workarounds for this vulnerability.
CVSS 5.3
CVE-2024-24818 WRITEUP MEDIUM WRITEUP
EspoCRM < 8.1.2 - Open Redirect via Password Change Page
EspoCRM is an Open Source Customer Relationship Management software. An attacker can inject arbitrary IP or domain in "Password Change" page and redirect victim to malicious page that could lead to credential stealing or another attack. This vulnerability is fixed in 8.1.2.
CVSS 5.9
CVE-2025-32390 WRITEUP HIGH WRITEUP
EspoCRM < 9.0.8 - Authenticated HTML Injection in Knowledge Base Articles
EspoCRM is a free, open-source customer relationship management platform. Prior to version 9.0.8, HTML Injection in Knowledge Base (KB) articles leads to complete page defacement imitating the login page. Authenticated users with the read knowledge article privilege can browse to the KB article and if they submit their credentials, they get captured in plain text. The vulnerability is allowed by overly permissive HTML editing being allowed on the KB articles. Any authenticated user with the privilege to read KB articles is impacted. In an enterprise with multiple applications, the malicious KB article could be edited to match the login pages of other applications, which would make it useful for credential harvesting against other applications as well. Version 9.0.8 contains a patch for the issue.

CVE-2025-52575 WRITEUP MEDIUM WRITEUP
EspoCRM < 9.1.7 - Unauthenticated Blind LDAP Injection via Wildcard Character
EspoCRM is an Open Source CRM (Customer Relationship Management) software. EspoCRM versions 9.1.6 and earlier are vulnerable to blind LDAP Injection when LDAP authentication is enabled. A remote, unauthenticated attacker can manipulate LDAP queries by injecting crafted input containing wildcard characters (e.g., *). This may allow the attacker to bypass authentication controls, enumerate valid usernames, or retrieve sensitive directory information depending on the LDAP server configuration. This was fixed in version 9.1.7.
CVSS 6.5
CVE-2025-52892 WRITEUP MEDIUM WRITEUP
EspoCRM < 9.1.7 - Denial of Service via Double Slash URL Path
EspoCRM is a web application with a frontend designed as a single-page application and a REST API backend written in PHP. In versions 9.1.6 and below, if a user loads Espo in the browser with double slashes (e.g https://domain//#Admin) and the webserver does not strip the double slash, it can cause a corrupted Slim router's cache. This will make the instance unusable until there is a completed rebuild. This is fixed in version 9.1.7.
