Description
Server-Side Request Forgery (SSRF) vulnerability in pdfmake versions 0.3.0-beta.2 through 0.3.5 allows a remote attacker to obtain sensitive information via the src/URLResolver.js component. The fix was released in version 0.3.6 which introduces the setUrlAccessPolicy() method allowing server operators to define URL access rules. A warning is now logged when pdfmake is used server-side without a policy configured.

Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:N)
Service keeps running; no real outage angle.
