CMK version:
Checkmk Enterprise Edition 2.3.0p24
Background:
Since this update it is only allowed to use a few html tags and no attributes:
Changes: With this Werk the Insert HTML section between body and table will be sanitized in the usual manner. So certain formatting tags like h1, b, etc. are still possible to use. To be precise: h1, h2, b, tt, i, u, br, nobr, pre, sup, p, li, ul, ol without any additional attributes are allowed.
except some attributs for the a-tag:
Links (a) are now allowed with the attributes href and target. The href needs to be either relative or when absolute must use one of the following URL schemas: http, https, mailto.
Problem:
Without being able to set the font size, the readability suffers extremely. Example:
So h1 and h2 are much bigger than the rest. Even pre creates bigger text than text inside of p or b.
Solution:
Allow the style attribute or use at least the same font size as in the default plugin output.
