SolidInvoice: Cleartext Storage of Sensitive Information
CVE-2026-46622 is a high-severity cleartext storage of sensitive information vulnerability in SolidInvoice, with a CVSS 3.1 base score of 8.1 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. Affected SolidInvoice versions: < 2.3.17. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.2% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.

Official description
SolidInvoice is an open-source invoicing platform. Prior to version 2.3.17, API tokens used to authenticate all REST API requests are stored as plaintext strings in the api_tokens database table. Any attacker who obtains read access to the database — through SQL injection, a leaked backup, a misconfigured replica, or insider access — immediately obtains all API credentials for every user with no further effort. This issue has been patched in version 2.3.17.

The underlying weakness: Cleartext Storage of Sensitive Information
The product stores sensitive information in cleartext within a resource that might be accessible to another control sphere.
How developers prevent this class of flaw
- When storing data in the cloud (e.g., S3 buckets, Azure blobs, Google Cloud Storage, etc.), use the provider's controls to encrypt the data at rest.
- In some systems/environments such as cloud, the use of double encryption (at both the software and hardware layer) might be required, and the developer might be solely responsible for both layers, instead of shared responsibility with the administrator of the broader system/environment.
