PHPSpreadsheet is a pure PHP library for reading and writing spreadsheet files. It's possible for an attacker to construct an XLSX file that links images from arbitrary paths. When embedding images has been enabled in HTML writer with `$writer->setEmbedImages(true);` those files will be included in the output as `data:` URLs, regardless of the file's type. Also URLs can be used for embedding, resulting in a Server-Side Request Forgery vulnerability. When embedding images has been enabled, an attacker can read arbitrary files on the server and perform arbitrary HTTP GET requests. Note that any PHP protocol wrappers can be used, meaning that if for example the `expect://` wrapper is enabled, also remote code execution is possible. This issue has been addressed in release versions 1.29.2, 2.1.1, and 2.3.0. All users are advised to upgrade. there are no known workarounds for this vulnerability.

PHPSpreadsheet: SSRF bypass via HTTP redirect in WEBSERVICE() domain whitelist
ghsa·2026-07-23
CVE-2026-59931 [HIGH] CWE-918 PHPSpreadsheet: SSRF bypass via HTTP redirect in WEBSERVICE() domain whitelist
PHPSpreadsheet: SSRF bypass via HTTP redirect in WEBSERVICE() domain whitelist
### Summary
The domain whitelist introduced in PhpSpreadsheet 5.4.0 for the `WEBSERVICE()` formula function can be bypassed via HTTP redirect. The whitelist validates only the initial URL's hostname, but `file_get_contents()` follows 302/301 redirects by default without re-validating the redirect target against the whitelist. This allows an attacker to reach internal services through a whitelisted domain that issues an HTTP redirect.
### Details
In `Calculation/Web/Service.php`, the `webService()` method validates the URL's host against a domain whitelist set via `Spreadsheet::setDomainWhiteList()`. If the host passes validation, the method calls `file_get_contents($url, false, $ctx)` to fetch the content.

CVE-2024-45291 [MEDIUM] CWE-22 PhpSpreadsheet allows absolute path traversal and Server-Side Request Forgery in HTML writer when embedding images is enabled
PhpSpreadsheet allows absolute path traversal and Server-Side Request Forgery in HTML writer when embedding images is enabled
### Summary
It's possible for an attacker to construct an XLSX file that links images from arbitrary paths. When embedding images has been enabled in HTML writer with `$writer->setEmbedImages(true);` those files will be included in the output as `data:` URLs, regardless of the file's type. Also URLs can be used for embedding, resulting in a Server-Side Request Forgery vulnerability.
### Details
XLSX files allow embedding or linking media. When
In `xl/drawings/drawing1.xml` an attacker can do e.g.:
```xml
```
And then, in `xl/drawings/_rels/drawing1.xml.rels` they can set the path to anything, such as:
```xml
```
or
```xml
```

CVE-2024-45048 [MEDIUM] Loft Data Grids - Moderately critical - Multiple vulnerabilities - SA-CONTRIB-2024-054
Title: Loft Data Grids - Moderately critical - Multiple vulnerabilities - SA-CONTRIB-2024-054
Vulnerability Type: Multiple vulnerabilities
Description: This module provides serialization formats for use by other modules. The module includes a version of phpoffice/phpspreadsheet which has multiple known security vulnerabilities.
Solution: If you use the Loft Data Grids module for Drupal 7.x, install one of: Loft Data Grids 7.x-2.7 - which removes support for the XLSX format, as the patched version requires PHP 8. Loft Data Grids 7.x-3.0 - which includes XLSX support, by requiring PHP 8 and Composer installation. See the module's README-file for more information.
