Security Vulnerabilities
Langfuse is an open source large language model engineering platform. In versions 3.146.0 and below, the /api/public/slack/install endpoint initiates Slack OAuth using a projectId provided by the client without authentication or authorization. The projectId is preserved throughout the OAuth flow, and the callback stores installations based on this untrusted metadata. This allows an attacker to bind their Slack workspace to any project and potentially receive changes to prompts stored in Langfuse Prompt Management. An attacker can replace existing Prompt Slack Automation integrations or pre-register a malicious one, though the latter requires an authenticated user to unknowingly configure it despite visible workspace and channel indicators in the UI. This issue has been fixed in version 3.147.0.

Horilla is a free and open source Human Resource Management System (HRMS). In versions prior to 1.5.0, a cross-site scripting vulnerability can be triggered because the extension and content-type are not checked during the profile photo update step. Version 1.5.0 fixes the issue.

Horilla is a free and open source Human Resource Management System (HRMS). An Improper Access Control vulnerability exists in Horilla HR Software starting in version 1.4.0 and prior to version 1.5.0, allowing any authenticated employee to upload documents on behalf of another employee without proper authorization. This occurs due to insufficient server-side validation of the employee_id parameter during file upload operations, allowing any authenticated employee to upload document in behalf of any employee. Version 1.5.0 fixes the issue.

Horilla is a free and open source Human Resource Management System (HRMS). Versions 1.4.0 and above expose unpublished job postings through the /recruitment/recruitment-details// endpoint without authentication. The response includes draft job titles, descriptions and application link allowing unauthenticated users to view unpublished roles and access the application workflow for unpublished jobs. Unauthorized access to unpublished job posts can leak sensitive internal hiring information and cause confusion among candidates. This issue has been fixed in version 1.5.0.

Horilla is a free and open source Human Resource Management System (HRMS). In version 1.4.0, the has_xss() function attempts to block XSS by matching input against a set of regex patterns. However, the regexes are incomplete and context-agnostic, making them easy to bypass. Attackers are able to redirect users to malicious domains, run external JavaScript, and steal CSRF tokens that can be used to craft CSRF attacks against admins. This issue has been fixed in version 1.5.0.

Horilla is a free and open source Human Resource Management System (HRMS). In version 1.4.0, the OTP handling logic has a flawed equality check that can be bypassed. When an OTP expires, the server returns None, and if an attacker omits the otp field from their POST request, the user-supplied OTP is also None, causing the comparison user_otp == otp to pass. This allows an attacker to bypass two-factor authentication entirely without ever providing a valid OTP. If administrative accounts are targeted, it could lead to compromise of sensitive HR data, manipulation of employee records, and further system-wide abuse. This issue has been fixed in version 1.5.0.

Horilla is a free and open source Human Resource Management System (HRMS). A critical File Upload vulnerability in versions prior to 1.5.0, with Social Engineering, allows authenticated users to deploy phishing attacks. By uploading a malicious HTML file disguised as a profile picture, an attacker can create a convincing login page replica that steals user credentials. When a victim visits the uploaded file URL, they see an authentic-looking "Session Expired" message prompting them to re-authenticate. All entered credentials are captured and sent to the attacker's server, enabling Account Takeover. Version 1.5.0 patches the issue.

sm-crypto provides JavaScript implementations of the Chinese cryptographic algorithms SM2, SM3, and SM4. A private key recovery vulnerability exists in the SM2 decryption logic of sm-crypto prior to version 0.3.14. By interacting with the SM2 decryption interface multiple times, an attacker can fully recover the private key within approximately several hundred interactions. Version 0.3.14 patches the issue.

sm-crypto provides JavaScript implementations of the Chinese cryptographic algorithms SM2, SM3, and SM4. A signature malleability vulnerability exists in the SM2 signature verification logic of the sm-crypto library prior to version 0.3.14. An attacker can derive a new valid signature for a previously signed message from an existing signature. Version 0.3.14 patches the issue.

go-tuf is a Go implementation of The Update Framework (TUF). Starting in version 2.0.0 and prior to version 2.3.1, if the TUF repository (or any of its mirrors) returns invalid TUF metadata JSON (valid JSON but not well formed TUF metadata), the client will panic during parsing, causing a denial of service. The panic happens before any signature is validated. This means that a compromised repository/mirror/cache can DoS clients without having access to any signing key. Version 2.3.1 fixes the issue. No known workarounds are available.
