Security readout for executives and security teams
Plain-English summary
LibreSpeed speedtest versions 5.2.0 through 5.2.4 have a cross-site scripting issue in results/stats.php. An authenticated remote user could manipulate the id parameter and affect browser-side content integrity. This is not listed as actively exploited in KEV, and the cited sources identify version 5.2.5 as the fix.
Executive priority
Schedule remediation during the next normal web application patch window unless the affected service is broadly user-accessible or handles sensitive trust relationships. The issue is moderate because it affects browser-side integrity, requires authentication, and has a named fixed release.
Technical view
CVE-2022-4957 is CWE-79 in LibreSpeed speedtest results/stats.php, triggered through the id argument. The CVSS 2.0 vector is AV:N/AC:L/Au:S/C:N/I:P/A:N, indicating network access, low complexity, required authentication, partial integrity impact, and no confidentiality or availability impact.
Likely exposure
Exposure is limited to LibreSpeed speedtest deployments running versions 5.2.0, 5.2.1, 5.2.2, 5.2.3, or 5.2.4, especially where authenticated users can access results/stats.php.
Exploitation context
The source bundle says the attack can be launched remotely and requires authentication per the CVSS vector. No provided source states active exploitation, and the CVE is not marked KEV.
Researcher notes
Evidence identifies affected versions and a specific patched release, but the source bundle does not describe the exact vulnerable code path beyond results/stats.php and id. Avoid asserting exploit availability or unauthenticated reachability without additional evidence.
Mitigation direction
- Upgrade LibreSpeed speedtest to version 5.2.5 or later.
- Apply patch commit a85f2c086f3449dffa8fe2edb5e2ef3ee72dc0e9 if maintaining a pinned fork.
- Confirm unsupported or modified deployments receive equivalent vendor-reviewed changes.
- If upgrade timing is unclear, check current LibreSpeed vendor guidance before accepting risk.
Validation and detection
- Inventory all LibreSpeed speedtest deployments and record installed versions.
- Confirm whether affected deployments expose results/stats.php to authenticated users.
- Verify fixed systems report version 5.2.5 or include the named patch commit.
- Review application logs for unusual id parameter activity without replaying payloads.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
