Apache HertzBeat: Improper Neutralization of Data within XPath Expressions
CVE-2026-24343 is a high-severity improper neutralization of data within xpath expressions vulnerability in Apache HertzBeat from Apache, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists version 1.8.0 as the first without the flaw, so updating Apache HertzBeat to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.75% chance of exploitation within 30 days, higher than 55% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Apache HertzBeat to 1.8.0 or a later version.

Official description
Improper Neutralization of Data within XPath Expressions ('XPath Injection') vulnerability in Apache HertzBeat. This issue affects Apache HertzBeat: from 1.7.1 before 1.8.0. Users are recommended to upgrade to version 1.8.0, which fixes the issue.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Improper Neutralization of Data within XPath Expressions
The product uses external input to dynamically construct an XPath expression used to retrieve data from an XML database, but it does not neutralize or incorrectly neutralizes that input.
How developers prevent this class of flaw
- Use parameterized XPath queries (e.g. using XQuery). This will help ensure separation between data plane and control plane.
- Properly validate user input. Reject data where appropriate, filter where appropriate and escape where appropriate. Make sure input that will be used in XPath queries is safe in that context.
