Prior to 6.7.3, an attacker who uses this vulnerability can craft a PDF which leads to the RAM being exhausted.

As a workaround, apply the patch manually.<\/p>\n<p>Severity: 0.0 | NA<\/p>\n<p>Visit the link for more details, such as CVSS details, affected products, timeline, and more&#8230;\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CVE ID : CVE-2026-27888 Published : Feb. 26, 2026, 12:42 a.m. | 27\u00a0minutes ago Description : pypdf is a free and open-source pure-python PDF library.
