- Fix
1.2.6- Upgrade serverpod_client to this version or later
Description
This bug bypassed the validation of TSL certificates on all none web HTTP clients in the serverpod_client package. Making them susceptible to a man in the middle attack against encrypted traffic between the client device and the server.
An attacker would need to be able to intercept the traffic and highjack the connection to the server for this vulnerability to be used.
Impact
All versions of serverpod_client pre 1.2.6
Patches
Upgrading to version 1.2.6 resolves this issue.
Affected versions
Pub
| Package | Vulnerable | Fixed in |
|---|---|---|
| serverpod_client | < 1.2.6 |
1.2.6 |
How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.

Weakness
CWE-295: Improper Certificate Validation
The product does not validate, or incorrectly validates, a certificate.
How to prevent it
- Architecture and Design, Implementation: Certificates should be carefully managed and checked to assure that data are encrypted with the intended owner's public key.
- Implementation: If certificate pinning is being used, ensure that all relevant properties of the certificate are fully validated before the certificate is pinned, including the hostname.
