Pghero: Generation of Error Message Containing Sensitive Information
CVE-2023-22626 is a high-severity generation of error message containing sensitive information vulnerability in Pghero from Pghero Project, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 3.1.0 as the first without the flaw, so updating Pghero to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.87% chance of exploitation within 30 days, higher than 59% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Pghero to 3.1.0 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
Affected products and versions
| Vendor | Product | Affected versions | Fixed in |
|---|---|---|---|
| Pghero Project | Pghero | 0.1.1 up to, but not including, 3.1.0 | 3.1.0 |

Official description
PgHero before 3.1.0 allows Information Disclosure via EXPLAIN because query results may be present in an error message. (Depending on database user privileges, this may only be information from the database, or may be information from file contents on the database server.)

The underlying weakness: Generation of Error Message Containing Sensitive Information
The product generates an error message that includes sensitive information about its environment, users, or associated data.
How developers prevent this class of flaw
- Handle exceptions internally and do not display errors containing potentially sensitive information to a user.
- Use naming conventions and strong types to make it easier to spot when sensitive data is being used. When creating structures, objects, or other complex entities, separate the sensitive and non-sensitive data as much as possible.
- Debugging information should not make its way into a production release.
