Bottles before 51.0 mishandles YAML load, which allows remote code execution via a crafted file.

A vulnerability, which was classified as critical, was found in john5223 bottle-auth. Affected is an unknown function. The manipulation leads to sql injection. The name of the patch is 99cfbcc0c1429096e3479744223ffb4fda276875. It is recommended to apply a patch to fix this issue. The identifier of this vulnerability is VDB-217632.

Bottle before 0.12.20 mishandles errors during early request binding.

OBottle 2.0 in \c\g.php contains an arbitrary file download vulnerability.

OBottle 2.0 in \c\t.php contains an arbitrary file write vulnerability.

The package bottle from 0 and before 0.12.19 are vulnerable to Web Cache Poisoning by using a vector called parameter cloaking. When the attacker can separate query parameters using a semicolon (;), they can cause a difference in the interpretation of the request between the proxy (running with default configuration) and the server. This can result in malicious requests being cached as completely safe ones, as the proxy would usually not see the semicolon as a separator, and therefore would not include it in a cache key of an unkeyed parameter.

redirect() in bottle.py in bottle 0.12.10 doesn't filter a "\r\n" sequence, which leads to a CRLF attack, as demonstrated by a redirect("233\r\nSet-Cookie: name=salt") call.

Bottle 0.10.x before 0.10.12, 0.11.x before 0.11.7, and 0.12.x before 0.12.6 does not properly limit content types, which allows remote attackers to bypass intended access restrictions via an accepted Content-Type followed by a ; (semi-colon) and a Content-Type that would not be accepted, as demonstrated in YouCompleteMe to execute arbitrary code.
