Integrated Publishing Toolkit: Improper Neutralization of Special Elements Used in a Template Engine
CVE-2026-71880 is a high-severity improper neutralization of special elements used in a template engine vulnerability in Integrated Publishing Toolkit from GBIF, with a CVSS 4.0 base score of 7.6 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 3.3.4 as the first without the flaw, so updating Integrated Publishing Toolkit to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.48% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Integrated Publishing Toolkit to 3.3.4 or a later version.

Official description
Interpretation of untrusted input in template engine in GBIF Integrated Publishing Toolkit versions before 3.3.4 allows remote authenticated attackers to access server-side files and state via template injection
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Improper Neutralization of Special Elements Used in a Template Engine
The product uses a template engine to insert or process externally-influenced input, but it does not neutralize or incorrectly neutralizes special elements or syntax that can be interpreted as template expressions or other code directives when processed by the engine.
How developers prevent this class of flaw
- Choose a template engine that offers a sandbox or restricted mode, or at least limits the power of any available expressions, function calls, or commands.
- Use the template engine's sandbox or restricted mode, if available.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: no, technical impact: total).
- Record last changed materially (score, affected products, status or references).
