| CVE-2026-113795 | 1 Py-pdf | 1 Pypdf | 2026-11-02 | 5.5 Medium |
| pypdf is a free and open-source pure-python PDF library. Prior to 6.20.0, accessing a crafted PDF stream with a large number of filters or multiple filters that pass around large amounts of data can cause large memory consumption. This issue is fixed in version 6.20.0. | ||||
| CVE-2026-113794 | 1 Py-pdf | 1 Pypdf | 2026-11-02 | 5.5 Medium |
| pypdf is a free and open-source pure-python PDF library. Prior to 6.20.0, an attacker can craft an incomplete PDF that ends inside a standard cross-reference table, causing pypdf to mishandle the unexpected end of file and enter an infinite loop. This issue is fixed in version 6.20.0. | ||||
| CVE-2026-113789 | 1 Py-pdf | 1 Pypdf | 2026-11-02 | 3.3 Low |
| pypdf is a free and open-source pure-python PDF library. Prior to 6.21.0, an attacker can craft a PDF that causes large memory usage or long runtimes when an application retrieves the document's form fields. This issue is fixed in version 6.21.0. | ||||
| CVE-2026-50053 | 2 Synacor, Zimbra | 2 Zimbra Collaboration Suite, Zimbra Collaboration Suite | 2026-11-02 | 8.7 High |
| A request attribute override vulnerability in Zimbra Collaboration Suite (ZCS) allows unauthenticated requests to /h/* to populate servlet attributes intended for trusted internal dispatch. RestFilter copies URL parameters specifying an authentication token, target account, target item and dispatch state into the request attributes consumed by the Classic Web Client. Combined with CVE-2026-10632 on ZCS 10.1.16, this allows an attacker to supply their own valid token and document identifiers and execute JavaScript in another user's signed-in browser session. ZCS 10.1.17 blocks that XSS chain by changing the document renderer, but retains the request attribute override. | ||||
| CVE-2026-59938 | 1 Py-pdf | 1 Pypdf | 2026-11-02 | 5.3 Medium |
| pypdf is a free and open-source pure-python PDF library. Prior to 6.14.0, an attacker can craft a PDF with declared image size values that are much too large compared to the actual data, causing large memory usage in pypdf image parsing. This issue is fixed in version 6.14.0. | ||||
| CVE-2026-59937 | 1 Py-pdf | 1 Pypdf | 2026-11-02 | 7.5 High |
| pypdf is a free and open-source pure-python PDF library. Prior to 6.14.0, an attacker can craft a PDF with repeated malformed cross-reference streams that cause pypdf to spend long runtimes recovering broken cross-reference table entries. This issue is fixed in version 6.14.0. | ||||
| CVE-2026-59935 | 1 Py-pdf | 1 Pypdf | 2026-11-02 | 7.5 High |
| pypdf is a free and open-source pure-python PDF library. Prior to 6.14.2, an attacker can craft a PDF with a page content stream containing a not terminated inline image that uses the ASCII85 or ASCIIHex filters, causing an infinite loop during parsing such as when extracting page text. This issue is fixed in version 6.14.2. | ||||
| CVE-2026-33123 | 1 Py-pdf | 1 Pypdf | 2026-11-02 | 6.5 Medium |
| pypdf is a free and open-source pure-python PDF library. Versions prior to 6.9.1 allow an attacker to craft a malicious PDF which leads to long runtimes and/or large memory usage. Exploitation requires accessing an array-based stream with many entries. This issue has been fixed in version 6.9.1. | ||||
| CVE-2025-62707 | 2 Py-pdf, Pypdf Project | 2 Pypdf, Pypdf | 2026-11-02 | 7.5 High |
| pypdf is a free and open-source pure-python PDF library. Prior to version 6.1.3, an attacker who uses this vulnerability can craft a PDF which leads to an infinite loop. This requires parsing the content stream of a page which has an inline image using the DCTDecode filter. This has been fixed in pypdf version 6.1.3. | ||||
| CVE-2023-46250 | 1 Py-pdf | 1 Pypdf | 2026-11-02 | 5.1 Medium |
| pypdf is a free and open-source pure-python PDF library. An attacker who uses a vulnerability present in versions 3.7.0 through 3.16.4 can craft a PDF which leads to an infinite loop. This infinite loop blocks the current process and can utilize a single core of the CPU by 100%. It does not affect memory usage. That is, for example, the case when the pypdf-user manipulates an incoming malicious PDF e.g. by merging it with another PDF or by adding annotations. The issue was fixed in version 3.17.0. As a workaround, apply the patch manually by modifying `pypdf/generic/_data_structures.py`. | ||||
| CVE-2026-48155 | 1 Py-pdf | 1 Pypdf | 2026-11-02 | 5.5 Medium |
| pypdf is a free and open-source pure-python PDF library. Prior to 6.12.0, an attacker who uses this vulnerability can craft a PDF which leads to large memory usage. This requires extracting text in layout mode with large character offsets. This vulnerability is fixed in 6.12.0. | ||||
| CVE-2026-48735 | 1 Py-pdf | 1 Pypdf | 2026-11-02 | 5.5 Medium |
| pypdf is a free and open-source pure-python PDF library. Prior to 6.12.1, an attacker who uses this vulnerability can craft a PDF which leads to large memory usage. This requires parsing large XMP metadata, possibly with lots of unnecessary elements. This vulnerability is fixed in 6.12.1. | ||||
| CVE-2026-48156 | 1 Py-pdf | 1 Pypdf | 2026-11-02 | 3.3 Low |
| pypdf is a free and open-source pure-python PDF library. Prior to 6.12.0, an attacker who uses this vulnerability can craft a PDF which leads to long runtimes. This requires cross-reference streams with /W [0 0 0] values and large /Size values. This vulnerability is fixed in 6.12.0. | ||||
| CVE-2026-54651 | 1 Py-pdf | 1 Pypdf | 2026-11-02 | 5.5 Medium |
| pypdf is a free and open-source pure-python PDF library. Prior to 6.13.1, an attacker who uses this vulnerability can craft a PDF which leads to an infinite loop. This requires merging a file with threads/articles into a writer. This vulnerability is fixed in 6.13.1. | ||||
| CVE-2025-55197 | 1 Py-pdf | 1 Pypdf | 2026-11-02 | 7.5 High |
| pypdf is a free and open-source pure-python PDF library. Prior to version 6.0.0, an attacker can craft a PDF which leads to the RAM being exhausted. This requires just reading the file if a series of FlateDecode filters is used on a malicious cross-reference stream. Other content streams are affected on explicit access. This issue has been fixed in 6.0.0. If an update is not possible, a workaround involves including the fixed code from pypdf.filters.decompress into the existing filters file. | ||||
| CVE-2025-62708 | 2 Py-pdf, Pypdf Project | 2 Pypdf, Pypdf | 2026-11-02 | 7.5 High |
| pypdf is a free and open-source pure-python PDF library. Prior to version 6.1.3, an attacker who uses this vulnerability can craft a PDF which leads to large memory usage. This requires parsing the content stream of a page using the LZWDecode filter. This has been fixed in pypdf version 6.1.3. | ||||
| CVE-2026-27628 | 1 Py-pdf | 1 Pypdf | 2026-11-02 | 7.5 High |
| pypdf is a free and open-source pure-python PDF library. Prior to 6.7.2, an attacker who uses this vulnerability can craft a PDF which leads to an infinite loop. This requires reading the file. This has been fixed in pypdf 6.7.2. As a workaround, one may apply the patch manually. | ||||
| CVE-2026-119205 | 1 Py-pdf | 1 Pypdf | 2026-11-02 | 5.5 Medium |
| pypdf is a free and open-source pure-python PDF library. Prior to 6.21.4, pypdf can enter an infinite loop when cloning or duplicating a crafted cyclic DictionaryObject. Clone traversal checked generated destination references rather than the original source references, allowing some source cycles to evade the visited-object check. This issue is fixed in version 6.21.4. | ||||
| CVE-2026-41313 | 1 Py-pdf | 1 Pypdf | 2026-11-02 | 6.5 Medium |
| pypdf is a free and open-source pure-python PDF library. An attacker who uses a vulnerability present in versions prior to 6.10.2 can craft a PDF which leads to long runtimes. This requires loading a PDF with a large trailer `/Size` value in incremental mode. This has been fixed in pypdf 6.10.2. As a workaround, one may apply the changes from the patch manually. | ||||
| CVE-2026-41312 | 1 Py-pdf | 1 Pypdf | 2026-11-02 | 6.5 Medium |
| pypdf is a free and open-source pure-python PDF library. An attacker who uses a vulnerability present in versions prior to 6.10.2 can craft a PDF which leads to the RAM being exhausted. This requires accessing a stream compressed using `/FlateDecode` with a `/Predictor` unequal 1 and large predictor parameters. This has been fixed in pypdf 6.10.2. As a workaround, one may apply the changes from the patch manually. | ||||
