CVE-2026-110748
Apache SIS: CWE-22: improper limitation of paths to GML, GeoTIFF, NADCON or NTv2 files
What happened?
This issue affects Apache SIS from version 0.7 through 1.6 inclusive. When a data file contains links to other files, Apache SIS opened these files regardless their paths. It was possible, for example, to specify a path to a local file. However, these files were always expected to be in some specific formats and the reading stops at the first parsing error, which makes this vulnerability unlikely to leak sensitive information. The impacted formats are:
* Geographic Markup Language (GML) with `xlink:href` attributes for other files in GML format. * Well Known Text (WKT) with parameter elements for datum shift grids in NADCON, NTv2 or RGF93 formats. * Landsat scene with paths to files for each band in the GeoTIFF format.
Users are recommended to upgrade to version 1.7, which fixes the issue by restricting the paths to the same directory as the file containing the references to other files, or to a predetermined directory for datum shift grids.
Affected software and versions
| Software | Version information | Fixed version |
|---|---|---|
| org.apache.sis:sis-metadataApache Software Foundation | affected: 0.7 to ≤ 1.6.0 | See vendor advisory |
Version information comes from the source record and can include unaffected products and exceptions. Distribution packages may contain backported fixes: an older upstream version alone does not prove a server is affected.
Is it being exploited?
This CVE was not listed in the CISA catalogue at our last retrieval. This does not establish that exploitation is absent.
How to respond
- Confirm the product, installed package version, and any configuration requirements in the vendor advisory.
- Follow the vendor’s remediation or workaround guidance in the references below. Structured fixed-version data is unavailable here; the publisher’s description may include a fix or workaround.
- Restart affected services if required, then verify the running version. Known exploitation may warrant investigation as well as patching.
