CVE-2026-26801

Exp

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.

Base score	Version	Severity	Vector	Exploitability	Impact	Score source
7.5	3.1	HIGH	`CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N` 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.	3.9	3.6	134c704f-9b21-4f2e-91b3-4a467353bcc0
