Package        : libphp-adodb
Version        : 5.20.9-1+deb9u1
CVE ID         : CVE-2021-3850
Debian Bug     : 1004376

It was found that in libphp-adodb, a PHP database abstraction layer
library, an attacker can inject values into the PostgreSQL connection
string by bypassing adodb_addslashes(). The function can be bypassed
in phppgadmin, for example, by surrounding the username in quotes and
submitting with other parameters injected in between.

For Debian 9 stretch, this problem has been fixed in version

We recommend that you upgrade your libphp-adodb packages.

For the detailed security status of libphp-adodb please refer to
