Focus on qbittorrent vulnerabilities and metrics.
Last updated: 08 Mar 2025, 23:25 UTC
This page consolidates all known Common Vulnerabilities and Exposures (CVEs) associated with qbittorrent. We track both calendar-based metrics (using fixed periods) and rolling metrics (using gliding windows) to give you a comprehensive view of security trends and risk evolution. Use these insights to assess risk and plan your patching strategy.
For a broader perspective on cybersecurity threats, explore the comprehensive list of CVEs by vendor and product. Stay updated on critical vulnerabilities affecting major software and hardware providers.
Total qbittorrent CVEs: 6
Earliest CVE date: 06 Mar 2017, 02:59 UTC
Latest CVE date: 02 Nov 2024, 06:15 UTC
Latest CVE reference: CVE-2024-51774
30-day Count (Rolling): 0
365-day Count (Rolling): 1
Calendar-based Variation
Calendar-based Variation compares a fixed calendar period (e.g., this month versus the same month last year), while Rolling Growth Rate uses a continuous window (e.g., last 30 days versus the previous 30 days) to capture trends independent of calendar boundaries.
Month Variation (Calendar): 0%
Year Variation (Calendar): 0.0%
Month Growth Rate (30-day Rolling): 0.0%
Year Growth Rate (365-day Rolling): 0.0%
Average CVSS: 3.28
Max CVSS: 7.5
Critical CVEs (≥9): 0
| Range | Count |
|---|---|
| 0.0-3.9 | 3 |
| 4.0-6.9 | 2 |
| 7.0-8.9 | 1 |
| 9.0-10.0 | 0 |
These are the five CVEs with the highest CVSS scores for qbittorrent, sorted by severity first and recency.
qBittorrent before 5.0.1 proceeds with use of https URLs even after certificate validation errors.
All versions of the qBittorrent client through 4.5.5 use default credentials when the web user interface is enabled. The administrator is not forced to change the default credentials. As of 4.5.5, this issue has not been fixed. A remote attacker can use the default credentials to authenticate and execute arbitrary operating system commands using the "external program" feature in the web user interface. This was reportedly exploited in the wild in March 2023.
In qBittorrent before 4.1.7, the function Application::runExternalProgram() located in app/application.cpp allows command injection via shell metacharacters in the torrent name parameter or current tracker parameter, as demonstrated by remote command execution via a crafted name within an RSS feed.
The UI Lock feature in qBittorrent version 3.3.15 is vulnerable to Authentication Bypass, which allows Attack to gain unauthorized access to qBittorrent functions by tampering the affected flag value of the config file at the C:\Users\<username>\Roaming\qBittorrent pathname. The attacker must change the value of the "locked" attribute to "false" within the "Locking" stanza. NOTE: This is an intended behavior. See https://github.com/qbittorrent/qBittorrent/wiki/I-forgot-my-UI-lock-password
WebUI in qBittorrent before 3.3.11 did not set the X-Frame-Options header, which could potentially lead to clickjacking.
WebUI in qBittorrent before 3.3.11 did not escape many values, which could potentially lead to XSS.
