CVE-2020-7059
This may lead to information disclosure or crash.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (7.40%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
When using fgetss() function to read data with stripping tags, in PHP versions 7.2.x below 7.2.27, 7.3.x below 7.3.14 and 7.4.x below 7.4.2 it is possible to supply data that will cause this function to read past the allocated buffer. This may lead to information disclosure or crash.
