| CVE-2026-41680 | Hig | 0.49 | 7.5 | 0.00 | | Apr 24, 2026 | Marked is a markdown parser and compiler. From 18.0.0 to 18.0.1, a critical Denial of Service (DoS) vulnerability exists in marked. By providing a specific 3-byte input sequence a tab, a vertical tab, and a newline (\x09\x0b\n)—an unauthenticated attacker can trigger an infinite recursion loop during parsing. This leads to unbounded memory allocation, causing the host Node.js application to crash via Memory Exhaustion (OOM). This vulnerability is fixed in 18.0.2. |
| CVE-2022-21681 | | 0.00 | — | 0.00 | | Jan 14, 2022 | Marked is a markdown parser and compiler. Prior to version 4.0.10, the regular expression `inline.reflinkSearch` may cause catastrophic backtracking against some strings and lead to a denial of service (DoS). Anyone who runs untrusted markdown through a vulnerable version of marked and does not use a worker with a time limit may be affected. This issue is patched in version 4.0.10. As a workaround, avoid running untrusted markdown through marked or run marked on a worker thread and set a reasonable time limit to prevent draining resources. |
| CVE-2022-21680 | | 0.00 | — | 0.01 | | Jan 14, 2022 | Marked is a markdown parser and compiler. Prior to version 4.0.10, the regular expression `block.def` may cause catastrophic backtracking against some strings and lead to a regular expression denial of service (ReDoS). Anyone who runs untrusted markdown through a vulnerable version of marked and does not use a worker with a time limit may be affected. This issue is patched in version 4.0.10. As a workaround, avoid running untrusted markdown through marked or run marked on a worker thread and set a reasonable time limit to prevent draining resources. |
| CVE-2021-21306 | | 0.00 | — | 0.01 | | Feb 8, 2021 | Marked is an open-source markdown parser and compiler (npm package "marked"). In marked from version 1.1.1 and before version 2.0.0, there is a Regular expression Denial of Service vulnerability. This vulnerability can affect anyone who runs user generated code through marked. This vulnerability is fixed in version 2.0.0. |
| CVE-2015-1370 | | 0.00 | — | 0.00 | | Jan 27, 2015 | Incomplete blacklist vulnerability in marked 0.3.2 and earlier for Node.js allows remote attackers to conduct cross-site scripting (XSS) attacks via a vbscript tag in a link. |
