CVE-2021-36359
OrbiTeam BSCW Classic before 7.4.3 allows exportpdf authenticated remote code execution (RCE) via XML tag injection because reportlab\platypus\paraparser.py (reached via bscw.cgi op=_editfolder.EditFolder) calls eval on attacker-supplied Python code.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.98%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
